Re: H323

I think netfilter can do the job.  You'll need a gatekeeper to do this:

Here's a few:
OpenGK gatekeeper translates between user aliases and IP addresses. Makes
your life easier.
OpenH232Proxy is a gatekeeper with built in proxy feature. It enables the
routing through the gatekeeper of the RTP traffic (audio and video) and the
T.120 traffic (data) so no traffic is directly exchanged between endpoints.
(This one is not in the distro yet.)
OpenMCU H.323 conferencing server lets you hold virtual conferences. simply
connect to openmcu server instead of connecting to another gnomemeeting
client, and you are ready to go. If installed on a firewall (and visible
from both sides), openmcu can serve as a proxy.


I've got OpenH232Proxy sort of working for my cams.
