I need help with following scenario: I have CUCM cluster in my private subnet with 192.168.1.0 addressing. Also I have 2821 gateway with 2 interfaces: one in 192.168.1.0 subnet and second interface resides in another subnet with real IPs. I need to create connection between CUCM and a H.323 GW in the outside network. How do I need to configure NAT on 2821 GW to allow inbound connections to pass to CUCM from the outside GW?
Thank in advance!
