You can't assign server ip directly. It will always default (AFAIK) to the lowest address on your computer. Hence since 212 is higher than 192, it will always have a 192 addy no matter what you do.

But from what I can tell, port-forwarding should be no problem in getting you from WAN to LAN.

I have posted a bug regarding the port assignment. I don't recognize your symptons but it's starting to sound like the same thing. Go to the bug forum and look for my -port bug posting. See if your problem looks similar. Then maybe you can "bump" that or post a new bug yourself.
