Hello,

If you are not using NAT, then just open up the high ports (> 1024) between the h.323 devices. You
maybe able to lock the port range down if supported by the h.323 devices, but m0n0wall doesn't
dynamically track h.323 connections.

If you are using NAT then things are less easy. h.323 embeds IP addresses and ports into the data
stream so unless the devices are NAT aware they may not work properly.

Not many firewalls that claim to support h.323 actually handle all the possible features. As a
protocol, h.323 is a very non-firewall friendly protocol (and SIP isn't much better).

Regards,

Kris.

  Has anyone used the m0n0wall for h.323 voice applications? I'm in the process of setting up a
large VoIP network and would like to keep the m0n0 in place as the firewall.

   

  Thanks.
