(refer to sig for specs) Here's the problem... iChat AV refuses to connect for audio and video conferences outside of our home network. For example, it works just fine if I am trying to connect with my dad downstairs from my bedroom. Whenever I try to connect to someone outside of our network, it always gives me the error: Failed to start video chat. (my name) did not respond. Or some message like that... Anyway, do you have any idea how to fix this? I've repaired permissions, trashed my prefs, and even opened the ports Apple's site tells me to. I would really love for this to work... it did for a couple times a while ago, but never again after that. Any help would be great. Thanks!
