Private Service Edge Deployment Guide for Linux

This deployment guide provides information on prerequisites, how to deploy a Private Service Edge on Red Hat Enterprise Linux 9.x (and 8.x), and post-deployment verification checks.

To learn more about support for CentOS 7.x, RHEL 7.x, and Oracle Linux 7.x, see End-of-Support for CentOS 7.x, RHEL 7.x, and Oracle Linux 7.x and CentOS 7 Configuration for Long-Term Zscaler Support.

  • Before deploying a Private Service Edge on any supported platform, Zscaler highly recommends reading the following information and making the necessary changes to your organization's environment, where applicable.

    Each Private Service Edge supports up to 500 Mbps of throughput. Use the information on this page to determine the Private Service Edge sizing requirements for your deployment. For example, with a 1 Gbps aggregate (i.e., total inbound and outbound) connection, you would need to deploy 2 to 3 Private Service Edges.

    • The following specifications are recommended by Zscaler for up to 500 Mbps throughput for each Private Service Edge.

      • Memory (RAM) and vCPU (for virtual machines) or CPU (for physical machines) cores:

        Active UsersMemoryvCPU or CPU Cores
        Up to 2,0008 GB (10 GB with ZDX)4 vCPUs or 4 CPUs
        Up to 4,00016 GB (18 GB with ZDX)8 vCPUs or 8 CPUs
        Up to 10,00032 GB (34 GB with ZDX)16 vCPUs or 16 CPUs

        To learn more, see the Private Service Edge Deployment Guide for your platform.

      • Disk Space: 64 GB (thin provisioned) for all deployment platforms
      • Network Card: 1 NIC (minimum)

      Depending on your deployment use case, each Private Service Edge must be able to accept incoming connections from either internal or external sources or both internal and external sources on TCP port 443. For example, if you enable for both remote and office users, each Private Service Edge needs to accept incoming connections from both internal and external endpoints running Zscaler Client Connector.

      Private Service Edges are reachable over the internet for remote users in a disaster recovery scenario, or when the Private Service Edge is the closest Service Edge.

      In the scenario where a Private Service Edge is deployed behind a firewall, the firewall performs destination network address translation (DNAT) for the Private Service Edge's private IP address. In this case, the flow of traffic is from Zscaler Client Connector to the Private Service Edge. The firewall then translates the destination public IP address that Zscaler Client Connector connects to on the private IP address of the Private Service Edge. The firewall advertises a public IP address on the internet. It is necessary to configure the public IP address advertised by the firewall as a publish IP of the respective Private Service Edge. In the case of disaster recovery, you must add this IP address as the A record for that Private Service Edge.

      Your firewalls must be configured to let the Private Service Edge establish outbound connections to the IP addresses of the Public Service Edge, and establish inbound connections from App Connectors and Zscaler Client Connectors.

      The following conditions apply to each Private Service Edge that is placed behind a firewall:

      • They must accept incoming connections from internal sources and remote users and on-premises users (as applicable and dependent on your use case) on TCP port 443.
      • They must have a unique private IP address that can be reached over the internal network.

      After a Private Service Edge is enrolled, an outbound TLS tunnel over TCP port 443 is established to the cloud infrastructure. This communication channel provides various functionality and includes the following traffic:

      • Periodic keepalives to the Public Service Edge
      • Policy configuration download
      • Private Service Edge software upgrades (upgrades are completed based on a weekly schedule)

      You can deploy additional Private Service Edges at any time, using the same provisioning key to add them to the existing Private Service Edge group, while ensuring network and internet connectivity. Private Service Edges are designed to scale elastically. You can deploy additional Private Service Edges in the same Private Service Edge group to increase the total throughput as required by your deployment. Zscaler recommends that you deploy Private Service Edges in pairs (N+1), where N is the number of Private Service Edges as per the sizing requirements. To learn more, see About Deploying Private Service Edges and Supported Platforms for Private Service Edges.

      After deployment, ensure that the Private Service Edge meets your sizing requirements. To learn more, see Verify Private Service Edge Sizing Specifications. If disk space fills up in the Private Service Edge, Zscaler recommends archiving files and creating more log space. To learn more, see Monitoring Private Service Edge Performance.

      Understanding Private Service Edge Throughput

      Throughput numbers are aggregate (i.e., total inbound and outbound). Each Private Service Edge supports up to 500 Mbps throughput. Private Service Edges communicate over the provided (default) gateway, which is most likely your ISP WAN broadband connection.

      Zscaler recommends that you check your existing VPN solution's average and peak throughput when determining your sizing requirements. Be sure to only account for user or client VPN traffic and not any site-to-site tunnel traffic.

      For example, if you have a 1 Gbps aggregate (i.e., total inbound and outbound) connection in your data center, you can use the 500 Mbps throughput guideline to make sure you have enough Private Service Edges to support the connection and have room for failover (N+1). In this case, you would need to deploy 2 to 3 Private Service Edges to support the 1 Gbps connection.

      The exact throughput can vary and depends on other network factors such as your internal network setup, latency, and whether you have double encryption, AppProtection, or ZDX enabled. Make sure that you have enough Private Service Edges to support the connection and room for failover (N+1).

      To horizontally scale your deployment, Zscaler recommends that you have more Private Service Edges with lower specifications rather than fewer Private Service Edges with higher specifications. For example, if you have fewer Private Service Edges with higher specifications and one fails, you could adversely affect more user application traffic or sessions than a smaller Private Service Edge that fails.

    • Before you begin any procedures within the Private Service Edge Deployment Guide for your platform, make sure that you have met all of the following prerequisites:

      • Intel x86_64/AMD64 based architecture
      • systemd
      • Root or sudo access to the system in order to configure a new package repository and install packages
      • DNS resolution and network access
      • A Private Service Edge provisioning key
      • A static MAC address
      Close

    • Private Service Edges can be deployed in different ways (as private cloud VMs, public cloud VMs, or OS packages), so the security features for each deployment type are slightly different.

      Operating System Security

      The Private Service Edge VMs distributed by Zscaler for use in private clouds are configured without any remotely accessible services running. Swap partitions are disabled on the Private Service Edge and its VMs to ensure that memory growths do not have an impact on the Private Service Edge performance. For enhanced security, you must use the passwd command to change the credentials on the default admin account. To learn more, see the Private Service Edge Deployment Guides for the platform you are using.

      Security Technical Implementation Guide (STIG) images are provided for AWS, GCP, Microsoft Azure, and VMware by default. To learn more, see Private Service Edge Software by Platform. The remaining rrivate and public cloud VM images provided by Zscaler are essentially unmodified operating systems (currently based on RHEL 9.x). You can patch these systems when necessary by using the standard yum OS update mechanism. Zscaler recommends that you harden the operating system, including the sshd-config file, on the VM images in accordance with your organization's security standards after initial deployment To learn more, see Managing Deployed Private Service Edges.

      To learn more about support for CentOS 7.x, see End-of-Support for CentOS 7.x, RHEL 7.x, and Oracle Linux 7.x.

      Due to the fact that vulnerabilities are regularly found in core open-source components such as DNS resolvers and the Linux Kernel, Zscaler recommends either patching or using new Zscaler-distributed VM images on a regular basis, or protecting Private Service Edges using firewall policies. Additionally, if you've installed the Private Service Edge as a package, Zscaler recommends that you take similar precautions.

      Some organizations choose to firewall or otherwise restrict outbound traffic to the internet from the data center. It is possible to deploy a Private Service Edge in such an environment as long as the Private Service Edge is able to reach all Zscaler data centers containing Public Service Edges. For firewall configuration information for your deployment, see config.zscaler.com/private.zscaler.com/zpa (for the private.zscaler.com cloud) or config.zscaler.com/zpatwo.net/zpa (for the zpatwo.net cloud).

      Firewall Requirements and Interoperability Guidelines

      All of the Zscaler data centers containing Public Service Edges must be allowed. A partial firewall configuration will result in connectivity problems for end users. Zscaler’s policy is to provide a 90 day notice for activating additional IP CIDR ranges, in order to provide organizations with sufficient opportunity for changing control policies.

      Because the service enforces TLS certificate pinning for both client and server certificates, all forms of inline or man-in-the-middle TLS interception or inspection must be disabled. Private Service Edge will not function if the TLS certificates presented by the Public Service Edges do not cryptographically verify against Zscaler-trusted public keys.

      By design, certificate verification is not configurable in order to maintain the integrity of the service, so ensure that *.prod.zpath.net is in your SSL bypass list for traffic originating from the Private Service Edge. This is necessary for allowing the Private Service Edge to resolve and reach Public Service Edges. Private Service Edge requires your firewall configuration to accept the incoming connections from the users. Also, if you need to allowlist additional Zscaler IP addresses, refer to config.zscaler.com/private.zscaler.com/zpa (for the private.zscaler.com cloud) or config.zscaler.com/zpatwo.net/zpa (for the zpatwo.net cloud). It might be possible to allowlist based on Zscaler cloud hostnames instead of IP addresses.

    • Private Service Edges require that the Zscaler Client Connector be at least on version 2.1.2.

      Close

    After you have met all of the prerequisites, you can deploy the Private Service Edge on a supported platform.

    Close

  • Before you deploy the Private Service Edge on a supported platform, you need to complete the following networking configurations:

    • By default, virtual machine-based Private Service Edges are configured to use DHCP networking on their primary interface. If necessary, you can configure a static IP address for a Private Service Edge.

      Close

    • If DHCP is not available, you can configure a static IP address on a VM-based Private Service Edge.

      1. Log in to the Private Service Edge console using your admin credentials.

      2. View the current connection profile.

        [admin@zpa-service-edge ~]$ nmcli connection show

      3. Modify the connection profile using the following format: <profile name> connection.id <new connection name>. For example:

        [admin@zpa-service-edge ~]$ sudo nmcli connection modify "Profile 1" connection.id LAN

      4. Review the current connection profile.

        [admin@zpa-service-edge ~]$ nmcli connection show

      5. Edit the profile using a static IP and a default gateway with the following format: <connection ID> ipv4.method manual ipv4.addresses <IP addresses> ipv4.gateway <gateway IP> ipv4.dns <DNS IP> ipv4.dns-search <domain name>. For example:

        $ sudo nmcli connection modify LAN ipv4.method manual ipv4.addresses 172.30.1.88/24 ipv4.gateway 172.30.1.1 ipv4.dns 172.30.1.254 ipv4.dns-search company.com

      6. To apply the changes, bring the connection connection ID back up. For example:

        [admin@zpa-service-edge ~]$ sudo nmcli connection up LAN

      7. Verify the IP address.

        [admin@zpa-service-edge ~]$ ip addr show

      8. Verify the default gateway.

        [admin@zpa-service-edge ~]$ ip route show default

      9. Verify the DNS settings.

        [admin@zpa-service-edge ~]$ sudo cat /etc/resolv.conf
      Close

    • If necessary, additional changes can be made to interfaces by configuring new ones using nmcli connection add con-name or by renaming existing ones using nmcli connection modify.

      1. Log in to the Private Service Edge console using your admin credentials.

      2. View the IP address.

        [admin@zpa-service-edge ~]$ ip addr show

      3. View the current connection profiles.

        [admin@zpa-service-edge ~]$ nmcli connection show

      4. Configure the interface's IP network using either a dynamic or static Ethernet configuration.

        For dynamic, modify the connection profile. For example:

        [admin@zpa-service-edge ~]$ sudo nmcli connection modify "Profile 1" ipv4.method auto

        For static, modify the connection profile and identify the IP addresses and gateway using the following format: <profile name> ipv4.method manual ipv4.addresses <address> ipv4.gateway <address>. For example:

        [admin@zpa-service-edge ~]$ sudo nmcli connection modify "Profile 1" ipv4.method manual ipv4.addresses 192.168.2.241/24 ipv4.gateway 192.168.2.254

      5. To apply the changes, bring the connection profile back up. For example:

        [admin@zpa-service-edge ~]$ sudo nmcli connection up "Profile 1"

      6. Reverify the IP address.

        [admin@zpa-service-edge ~]$ ip addr show

      7. Reverify the new connection.

        [admin@zpa-service-edge ~]$ nmcli connection show
      Close

    • To add static routes to the interface control files for a Private Service Edge:

      1. Log in to the Private Service Edge console using your admin credentials.

      2. Edit the static route for an existing Ethernet connection using the following format: <profile name> ipv4.routes <address and gateway>. For example:

        [admin@zpa-service-edge ~]$ sudo nmcli connection modify "Profile 1" +ipv4.routes 192.168.2.241/24 10.10.10.1

      3. To apply the changes, bring the connection profile down and then back up. For example:

        [admin@zpa-service-edge ~]$ sudo nmcli connection down "Profile 1"
        [admin@zpa-service-edge ~]$ sudo nmcli connection up "Profile 1"

      4. Verify the new route is added.

        [admin@zpa-service-edge ~]$ ip route
      Close

    • DNS resolution is critical for the successful operation of the Private Service Edge. Private Service Edges must also be able to resolve external DNS names, such as those of the cloud infrastructure.

      1. Log in to the Private Service Edge console using your admin credentials.

      2. View the current connection profile.

        [admin@zpa-service-edge ~]$ nmcli connection show

      3. Modify the DNS settings using the following format: <profile name> ipv4.dns <nameserver IP>. For example:

        [admin@zpa-service-edge ~]$ sudo nmcli connection modify "Profile 1" +ipv4.dns 192.168.2.241

      4. To apply the changes, bring the connection profile down and then back up. For example:

        [admin@zpa-service-edge ~]$ sudo nmcli connection down "Profile 1"
        [admin@zpa-service-edge ~]$ sudo nmcli connection up "Profile 1"

      5. Verify the nameservers record was added.

        [admin@zpa-service-edge ~]$ sudo cat /etc/resolv.conf
      Close

    • To configure Private Service Edges to use internal NTP servers:

      1. Log in to the Private Service Edge console using your admin credentials.

      2. Edit the /etc/chrony.conf file. Use an editor, such as vi.

        [admin@zpa-service-edge ~]$sudo vi /etc/chrony.conf

      3. Add your internal NTP servers to the list. For example:

        server 0.zscaler.pool.ntp.org iburst
server 1.zscaler.pool.ntp.org iburst
server 2.zscaler.pool.ntp.org iburst
server 3.zscaler.pool.ntp.org iburst

      4. To apply the changes, restart the chrony daemon using the following command:

        [admin@zpa-service-edge ~]$ systemctl restart chronyd
      Close

    • If your traffic is going through a proxy, you must manually configure the Private Service Edge to work through that proxy. The following procedure allows the Private Service Edge to communicate with the broker by using CONNECT requests through a standard HTTP proxy server.

      To configure the Private Service Edge to work through an explicit proxy:

      1. Log in to the Private Service Edge console using your admin credentials.

      2. Create a file named, /opt/zscaler/var/service-edge/proxy. Use an editor, such as vi.

        [admin@zpa-service-edge ~]$ sudo vi /opt/zscaler/var/service-edge/proxy

        Enter the proxy information using the following format: <Proxy Hostname or IP Address>:<Proxy Port> (e.g., 192.0.2.0:0).

      3. To apply the changes, restart the Private Service Edge using the following command:

        [admin@zpa-service-edge ~]$ sudo systemctl restart zpa-service-edge

      The Private Service Edge will attempt to create a TLS session through the proxy specified previously.

      Close

    • If you want to configure yum to communicate through an HTTP proxy server, refer to the CentOS and Red Hat documentation. To learn more about support for CentOS 7.x, RHEL 7.x, and Oracle Linux 7.x, see End-of-Support for CentOS 7.x, RHEL 7.x, and Oracle Linux 7.x.

  • This article provides migration instructions to replace CentOS 7 instances with Red Hat Enterprise Linux 9 (RHEL 9). The enrollment and provisioning of new Private Service Edges can be automated in a few steps using Terraform (IaC) or Container Orchestration to further simplify deployment.

    To learn more about support for CentOS 7.x, see End-of-Support for CentOS 7.x, RHEL 7.x, and Oracle Linux 7.x.

    Note the following requirements for successfully migrating from CentOS 7 to RHEL 9:

    • Use a fresh install for all deployments.
    • The EL9 repository must be used with RHEL 9 base OS. Older platform binaries (EL7/EL8) are not supported.
    • Ensure that the /opt/zscaler/var folder is empty before install.
    • Yum upgrades from EL7/EL8 to RHEL9 are not supported.
    • Requires ESXi version 7.0 Update 2 or newer, including ESXi 8.x. To learn more about ESXi support, see End-of-Support for VMware vSphere Hypervisor (ESXi) Version 5.5.

    Use the following steps to migrate from CentOS 7 to RHEL 9:

    1. Use a current provisioning key or create a new Private Service Edge group with a provisioning key for each location.
    2. Verify the version profile is Default, Previous Default, or New Release by doing one of the following:

      • If Persist Local Version Profile is Disabled, check the Version Profile inherited from the tenant.

      • If Persist Local Version Profile is Enabled, select an option for the Version Profile.

    3. Follow the step-by-step guide to deploy new VMs using the RHEL 9 images and newly created provisioning keys. Ensure the yum repository is pointing to the new RHEL 9 link: https://yum.private.zscaler.com/yum/el9

      Only RHEL 9 repositories and RPMs are supported on RHEL 9.

    4. Add trusted networks and enable Publicly Accessible (if applicable) on the new Private Service Edge groups.

    5. (Optional) Disable the Private Service Edge groups 15 minutes prior to the regional off-hours maintenance window to allow connections to gradually drain down.

    6. During regional off hours, remove trusted networks and disable public access (if applicable) on CentOS 7 Private Service Edge groups.

    Close

  • To deploy a Private Service Edge, you need to download the RPM package on the Private Service Edge you're deploying. However, in some cases, the Private Service Edge might be unable to download the package, and you'll have to download it on a server instead. Choose one of the following deployment options depending on your situation.

    • If the Private Service Edge can download the RPM package:

      1. Log in to the Private Service Edge console with sudo access or directly as the root user.
      2. Create a file named /etc/yum.repos.d/zscaler.repo. Use an editor, such as vi.
      [admin@zpa-service-edge ~]$ sudo vi /etc/yum.repos.d/zscaler.repo

      Enter the following content within the file:

      [zscaler]
name=Zscaler Private Access Repository
baseurl=https://yum.private.zscaler.com/yum/el9
enabled=1
gpgcheck=1
gpgkey=https://yum.private.zscaler.com/yum/el9/gpg

      For Red Hat Enterprise Linux 9-based deployments, you must use https://yum.private.zscaler.com/yum/el9 as the baseurl.

      1. Install the package using the yum install command.
      [admin@zpa-service-edge ~]$ sudo yum install zpa-service-edge
      1. The Private Service Edge console asks for confirmation twice. Enter y both times and ensure that the GPG fingerprint matches, a6fe 2422 fce7 e8ac 672e 9e51 644e a315 8765 e1dd, as highlighted in green within the example below:
