I have the folowing setup for an AG Venue Server and an AG Bridge Server:
- the Venue Server: one machine running Fedora Core 4 and AGTK 2.4. This 
machine has the internal IP and the domain name 
silicon.fe.up.pt. This machine has linked to it the real IP address I don't know exactly what this means in terms of 
networking, I just asked my network admin to make my machine visible to 
the Internet and he told me that my machine can be seen from the 
Internet with this address and also by its name silicon.fe.up.pt. Ports 
8000, 8002, 8004, 8006 TCP are opened for this machine.
- the Bridge Server is running Slackware 10 and AGTK 2.4. Same as above, 
internal IP is, external IP is and name 
poly.fe.up.pt. Ports 50000-50010 UDP are opened.

I've conducted some tests. On the internal network everything works 
fine. From outside, people can connect to my Venue Server using 
https://silicon.fe.up.pt:8000/Venues/default , they see the BridgeServer 
and can choose Unicast, however they do not appear in my RAT window and, 
of course, I cannot talk to them. Multicast is not an option. Also no 
output in the terminal of the BridgeServer for machines trying to 
connect from outside. For those on the local network I have the normal 

Any thoughts about why the Bridge Server is not doing its job?
