iChat : insufficient badnwidth - connecting 2 machines on ..

Is this error basically used whenever 2 clients can't connect? I read
elsewhere that it often has nothing to do with actual bandwidth.
Should I be able to connect 2 machines for video chat if they are both
behind the same home router? Would opening ports or UPnP ake a
difference? It would seem that if I have 2 machines on the same home
router that I might not be able to do video chat between them. If not,
how can I test then? Perhaps I need to put one of them in the dmz?

Thanks,
John

Are you connecting via Bonjour, or trying to connect via .Mac or
AOL AIM account?

If Bonjour, it should work fine. If via .Mac or AIM, then the
problem is that because both clients are sending requests to a
server on the internet, they both look like they have the same IP
address (the one assigned to your router), and it becomes
difficult for one to make a direct connection to the other via
your common IP address.

If you are not seeing each Mac in iChat via Bonjour, then either
you do not have it enabled in iChat, or you have multiple
cascading routers in your home (for example, Cable/DSL Router
talking to your broadband connection and another WiFi base station
router, with one Mac connected to the Cable/DSL Router and the
other connected to the WiFi base station; if this is the case,
then disable routing features in the WiFi base station).
