Add an IP Pool

To configure IP address pools for remote access VPNs, complete the following steps:

  1. Navigate to Connect > End User Connectivity > Virtual Private Network.
  2. Under Regions and IP Pools, click Manage.

    This opens the Regions and IP Pools pane. Each region requires unique IP pools for endpoint device remote access VPN connections.

  3. Click Add IP Pool to add a set of IP addresses for a VPN profile.

  4. Configure the Parameters for this IP pool, including its mapped region, DNS servers, and IP addresses.

    1. Select a Region for this IP pool from the drop-down.

    2. Enter a Display Name for the region.

    3. Choose a pair of DNS Servers from the drop-down, or click Add to add a new DNS pair.

    4. Add a System IP Pool for administrative access to remote services. The System IP Pool is the network from which Secure Access as a system obtains an IP address to talk to services hosted in customer data centers.

      • You can add IP ranges from /28 to /21, up to five subnets.
      • Note that the subnets added for System IPs limit the overall amount of IPs available to the regional IP pools.
  5. Scroll down to IP Pools and click Add IP Pool to add IP pools for the selected region.

  6. Configure the Add IP Pool parameters:

    • Add a meaningful IP Pool name. An distinctive, easily recognized name is helpful when assigning IP pools and configuring VPN profiles.

    • Add IPv4 subnets for use with remote access VPN endpoints. Each endpoint will be assigned an IP address from the defined IP pool. Supports ranges from /28 to /16. You can add multiple comma-separated ranges.

    • Optionally, you can add IPv6 subnets for use with remote access VPN endpoints. Each endpoint will be assigned an IP address from the defined IP pool. Supports ranges from /112 to /124. You can add multiple comma-separated ranges.

  7. Click Save & Add IP Pool when you are done. Click Save to save any edits to an IP address pool.
