Which action is required for a firewall configuration on a Mobile and Remote Access through Cisco Expressway deployment?

• A.The external firewall must allow these inbound connections to Expressway: SIP: TCP 5061; HTTPS: TCP 8443: XMPP: TCP 5222; Media: UDP 36002 to 59999.
• B.The internal firewall must allow these inbound and outbound connections between Expressway-C and Expressway-E. SIP: HTTPS (tunnelled overSSH between C and E): TCP 2222; TCP 7001; Traversal Media: UDP 2776 to 2777 (or 36000 to 36011 for large VM/appliance): XMPP: TCP 7400.
• C.The traversal zone on Expressway-C points to Expressway-E through the peer address field on the traversal zone, which specifies the Expressway-E server address. For dual NIC deployments, set the Expressway-E address using an FQDN that resolves the IP address of the internal interface
• D.Do not use a shared address for Expressway-E and Expressway-C, as the firewall cannot distinguish between them If static NAT for IP addressing on Expressway-E is used, ensure that any NAT operation on Expressway-C does not resolve the same traffic IP address Shared NAT is not supported.
