Matt, I'd love to chat and see if my NAT/firewall is correctly configured,
just so I can rule out my end and focus on solving the problem.

Despite the fact I am not using any video, I can concur that port forwarding
may be required.
A while ago I tried Yahoo messenger to do an audio chat and indeed I
needed to find out which port (number) it wanted to use for the audio and then enter this information into my ADSL router's port forwarding table, stipulating which internal (local) IP address to which that port would be forwarded to, this G4 in fact.

So Yahoo did not need port forwarding for text chats but it did for streaming the audio. Skype does not need port forwarding for streaming audio but it may need it for video?

HTH
