Re: [GnomeMeeting-list] Gnomemeeting behind a Cisco Nat Firewall

["Christian Nabski" <christian nabski emd be>]

What I think those routers do :
You can connect everywhere inside --> outside.
And if you enable a parameter like netmeeting in  them they trigger the 
incoming ports.
eg if a connections comes in on 1720 other ports are opened by a trigger.
