UT3 v1.1 NAT fix
January 29, 2008 at 01:04 by Mike McQuaid
I still keep a Windows partition around, partly to see what the competition is up to and partly to play games. One of my pleasures recently has been playing Unreal Tournament 3. A Linux port is in progress but has yet to be delivered so I’m biding time with the Windows version.
Try as I might I couldn’t get the NAT traversal to work with the v1.1 patch. I read various blog posts informing me to use a STUN server but that seemed unnecessarily overkill.
I finally worked out the problem this evening! Epic added STUN support to v1.1 and added initialised the server variable in the configuration file to a dummy value which turns on the STUN NAT mode, breaking the existing NAT support.
To fix this change the:
“StunServerAddress=stunserver.org”
line in “My Documents\My Games\Unreal Tournament 3\UTGame\Config” to:
“StunServerAddress=”
and it should all just work

buy a ps3 it is a more politically correct
Politically correct? If you are going to go down that route then Sony are as bad (if not worse) than Microsoft with regard to DRM etc. Unless you are saying I just can’t play proprietary games at all?
Nice troll. Try harder next time.
i got a ps3 for gaming too, i love to never have this f**king windows install war around.
definitly a worthy purchase
I don’t like the Playstation controllers, especially for FPSs. If I get a console it’ll be a 360.
Hi Mike,
I will test that.
Thanks a lot for sharing this information. I tried running a stunserver like some other guy suggested and it did not work. This did work, however, and is also working here for v1.2.
I tried this with version 1.2 and still a no go. It did get rid of the dmz error in UT3. I also have the ports forwarded. I am at a loss.
