i'm not sure this is the correct forum but any help it's welcome.
I have a 857 router ios 12.4(4)T with no acl, and no firewall configured, i need to apple ichat for video but all the time i get no response from my client. Apple says this:
"Network address translation (NAT) is a popular method for sharing an Internet connection on small networks. Airport base stations and many other household routers have the option of using NAT. In many cases, NAT is the default setting. iChat can establish audio and video connections over NAT, which may allow iChat to succeed where similar teleconference applications cannot."
i'm using only 1 external ip address share thru NAT
