Iptables and H.323

["Alejandro Cabrera Obed" <sisdis@xxxxxxxxxxxxxx>]

Hi folks !!!

I'll install gnugk (it's a H.323 gatekeeper) in my firewall in order to
register some internal and external OpenPhone clients to talk among them.

I have Linux Red Hat 9 with iptables-1.2.7a-2.

I ask you: what protocols and ports do I have to install in order to
establish the communication among H.323 LAN and Internet clients ???

Thanks a lot,

Alejandro Cabrera
