I'm trying to setup a videoconference and I have a 2801 router (12.4(18c)) with NAT configuration between units but It doesn't work. I captured some packets with sniffer and I can see that units are trying to send voice and video information to the real IP address (not natted ip address in router). NAT and h323 is supported in Cisco? Should I apply a specific configuration in router?
Please let me know your comments.
