Expressway-E Traversal Client Zone Configuration

C.

In this scenario, the Expressway-E is configured with a single NIC and Network Address Translation (NAT). To allow the Expressway-C traversal client zone to connect to the Expressway-E, the following steps must be taken:

1. Configure the Expressway-E The Expressway-E must be configured with the correct NAT address, and the appropriate firewall rules must be in place to allow traffic to pass through to the Expressway-C.

2. Configure the Expressway-C Traversal Client Zone The Expressway-C traversal client zone must be configured to allow communication with the Expressway-E. The following configuration is required:

• Peer address: This must be set to the Expressway-E NAT address, not the LAN IP address.
• Zone profile: The default zone profile can be used, or a custom profile can be created and applied to the traversal client zone. This will depend on the specific requirements of the deployment.
• TLS verify: This should be enabled to ensure secure communication between the Expressway-C and Expressway-E.

By configuring the Expressway-C traversal client zone with the correct peer address and zone profile, and enabling TLS verify, the Expressway-C will be able to connect to the Expressway-E and establish a secure communication link for traversal calls.
