iChat video chat not working!!

[zblaxberg]

Whenever I log onto Ichat, I try to have a video chat or audio chat however it will always have an error. What do I do? It says chat ended with error -20

Make sure routers/firewalls aren't blocking the required ports for iChat A/V.

This might help: "Using iChat with a firewall or NAT router"
