Re: [GnomeMeeting-list] Problems using Microtelco....

[John Francis Lee <jfl robinlea com>]

Hello Krist,

I ad troubles with microtelco too. I think I have them pretty well
straightened out now.

But I don't think it's microtelco that's your problem, yet.

I think that the h323 protocol put's ip addresses inside the packet
payloads as well as in the packet headers.

So you need to do more than forward ports, if you're doing nat inside
your netgear router. You need to reach inside the data portion of the
packets and nat the addresses there as well.

I don't think that your netgear can do this.

I do think there are hacks in modules for iptables and ipchains that can
do this, if you use a linux for a gw.

Maybe you had nat turned off on your netgear router when you first
tested?
