UT2004: broadcast a VPS IP to the master server?

Hey all

I got a UT2004 server working just fine via my public IP + Port forwarding on my router.

I also got it working just fine using Pangolin reverse proxy / tunnel connection via my VPS. I can forward the corresponding ports through pangolin and access my home server's game instance via my VPS' IP, which is really neat since I don't need to have local ports opened.

However, the VPS' IP isn't beign broadcast to the master server, which is a pity.

Is there any way to broadcast a different IP to the master server?

Any help much appreciated
