Set Up Firewall Traversal Pair

with Cisco Expressway · IT Infrastructure Management

Create a traversal server zone on the E and a matching client zone on the C.

  1. Create the traversal server zone on the Expressway-E so it can provide firewall traversal services to a traversal client.
  2. Create the matching traversal client zone on the Expressway-C that connects to the Expressway-E using the same shared connection credentials.
  3. Read zone connectivity status on the Expressway-C and confirm the new client zone is present so the traversal pairing can be verified.
What you'll need to have ready
  • edgeHost: FQDN or IP of the Expressway-E node (server variable host).
  • controllerHost: FQDN or IP of the Expressway-C node (server variable host).
  • username: Administrator username for HTTP Basic auth on both nodes.
  • password: Administrator password for HTTP Basic auth on both nodes.
  • serverZoneName: Name for the traversal server zone created on the Expressway-E.
  • clientZoneName: Name for the traversal client zone created on the Expressway-C.
  • sharedUsername: Connection credentials username shared by both zones.
  • sharedPassword: Connection credentials password shared by both zones.
  • edgeAddress: FQDN or IP of the Expressway-E that the client zone connects to.
