I am going to have to do something like this very soon. I have two H.323 endpoints using RFC1918 addressing on my network that are going to have to be able to communicate with the rest of the world sometime soon. Since I was told that using NAT doesn't work with H.323 (apparently it does to some degree, as you have it partially working), the only solution I knew of until now was to set up a MCU (Multipoint Connection Unit) in my DMZ so that my internal endpoints and any external clients could communicate through it. Unfortunately, this is an extremely expensive proposition, as the only MCU software available that I know of (from White Pine Software) is several thousand dollars, and MCU hardware is considerably more expensive than that. I just took a look at this PhonePatch software, and it looks like it will do what I need. I don't suppose anybody knows of any free or better yet open-sourced equivalents? -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
