I'm stuck with netmeeting too, I need to be able to go through a SME 4.1.2 box to a M$ server on the otherside (running netmeeting 3.01). I have ipmasqadm portfw set up to forward the ports (1720, 1503) and the ip_masq_h323 module loaded as normal, it does get a connection, but then rejects. The /var/log/messages comes up with the following:
Feb 6 11:56:27 cow1 kernel: masq_h323_done_1
Feb 6 11:56:27 cow1 kernel: masq_h323: h245 status (0=unregistered, 1=registered) = 1
Feb 6 11:57:08 cow1 kernel: masq_h323_init_1
Feb 6 11:57:08 cow1 kernel: masq_h323_init_1: found an old h245 app; n_attach forced to 0
Feb 6 11:57:08 cow1 kernel: masq_h323_init_1: the old h245 app is successfully unregistered.
Feb 6 11:57:08 cow1 kernel: masq_h323_in: H.245 Port is at: 0
So it appears something good is happening, but the connection ain't getting forwarded. I've played with what I think is everything, bar updating the masq_h232 module.
Something I'm missing here? Like I've toyed with ipchains, but even with a default 'accept' policy, and removal of 'deny' entries doesn't help.
