Which actions required for a firewall configuration on a Mobile and Remote Access

through Cisco Expressway deployment?

Options:

A.

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

B.

The external firewall must allow these inbound connections to Expressway: SIP: TCP 5061; HTTPS: TCP 8443; XMPP TCP 5222; media: UDP 36002 to 59999

C.

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

D.

The internal firewall must allow these inbound and outbound connections between

expressway - c and Expressway-e :sip;HTTPS(tunneled over SSH between C and E.
