so, as you can tell from some of my posts, we are thoroughly testing this in our environment, preparing for a purchase... We are deploying 250 laptops on Microsoft's Direct Access. Now directaccess is an ipv6 technlology. I searched, and found some discussion on ipv6, and know it is being worked on. I'm not going to get into that, but instead discuss directaccess with UAG, and it's 6to4 technologies, and translation. We have been able to get several other things working on our direct access clients by using the 6to4 translation. The only thing is instead of ip addresses, you have to use names, and the 6to4 does the translation for you. You can also use ipv6 addresses which you can find out by pinging the name. on the 3cxphone5, I'm guessing this is not an option. I've tried turning off auto provisioning, and setting the server with a name, instead of an ip address, and no joy. I tried turning on the 3cx tunnel with that setup, also no connection. I tried downloading the 3cx proxy manager, and testing it with it's outside interface as both ipv4, and ipv6....none of the settings worked. the only way I got a 3cxphone5 to connect, was by telling it I was out of the office, and using the external ip(which forced the connection outside directaccess). This wouldn't work if we were doing directaccess with forced tunneling, instead of split tunneling. I've tried setting up a 3cx phone system 10, on a 2008 server, with an ipv4, and ipv6 address. I also have a 3cx system9 server on windows xp, with an ipv4 only address, trying to force UAG to do the NAT 6 to 4. can anyone think of a way I can get the 3cxphone to connect to 3cx system9 directly over a directaccess client?
