I looked at it carefully before posting, but I could get or figure out a 
practical solution to my problem using it.

Excuse me if I am wrong, I am trying to decode the NAT, port, channel 
concepts, but since we have both DSL connection through french public 
provider with standalone workstation, aren't we automatically behind at least 
two NAT from the provider ?

Are the following lines in my firewall configuration file 
(/etc/shorewall/rules)  concerning channel H.245 appropriate to enable 
connection ?
# H.245 Port Range: TCP port range [30000-30010],
ACCEPT          fw      net     tcp     30000:30010
ACCEPT          net     fw      tcp     30000:30010

This said, what kind of solutions do we have to establish the communication ?
(If the problem is on the Windows side, would an other software than 
Netmeeting solve the problem ?)


Thank you
