Description:I've made a patch so you can call asterisk boxes from behind NAT using H.323. It uses the same logic as SIP, to use it just put nat=1 in h323.conf under the user's profile. The only issue is with MS's internet sharing which tries to proxy any connections on port 1720.
I suggest you change port if you have this issue.

Good job adam... Hope it works as well as you say.  :P  I don't have nat or I would test it.  But msg JerJer since he does chan_h323

Merged untested into cvs.

This may work for the RTP channel but the other channels that get setup (ie H.245) would still get setup to the private IP address.

I cannot find any major issues with this unless you are NOT using the RFC2833 type DTMF payload.
