[GnomeMeeting-list] Gnomemmeting behind another computer : no sound and no video

[Amandine <fab4am free fr>]

Hello,

I'm using Ubuntu hoary (5.04) and gnomemeeting 1.2.1. My computer can go 
on the internet thanks to LAN with another computer which owns the 
Internet connection, and which is on Windows XP.
To get gnomemeeting working, I had to forward many ports with AnalogX 
PortMapper :
- TCP port 1720
- TCP port range [30000-30010]
- UDP port range [5000-5016]
- UDP port range [5020-5023]

It works, as i can receive calls, and chat, but i can hear nothing, and 
video doesn't work too. My correspondant doesn't see me and can't hear me.

I don't really understand where's the problem.

If you could help me, i'd be very thankful :)

Amandine

P.S.: Sorry, I'm really confused about my bad english... I'm just french!
