Well, that doesn't seem to work for me.  If I only forward TCP/1720 to my 
workstation, then I see an incoming call request, but the session is unable 
to open up.  If, however, I forward TCP/1720 as well as UDP/TCP/1024-65535 to 
the workstation, the session opens right up.

So, is it safe to assume, then, that the Linksys BEFSR41 router does *not* 
natively support H323?

I've tried the above port forwarding with and without the IP translation 
turned on within GM, but get the same problems.

That did not work.

I guess that the really frustrating thing is that it works fine when I'm 
talking to a netmeeting client, but hangs when I'm talking to a gnomemeeting 
one.  Gnomemeeting is so vastly better (IMHO) than nm that I just want to put 
nm completely behind me entirely.

I'll try some more experimenting.  If you have any more suggestions, I'd sure 
like to hear them.  I'll gladly offer up a free signed copy of my second 
O'Reilly book, "Secure Coding: Principles and Practices", to anyone that is 
able to solve this problem for me, as soon as the book is out of the printer 
(in late June).
