port forwarding -- which ports :)

[darksky]

Is there an official guide/document that describes exactly which ports needs to be forwarded to a ut3 server that's behind a router?

I looked at my firewall logs for incoming connections when I did a direct connect (i.e. removed the router from the network temporarily) and found the following incoming requests in 30 seconds:

(All UDP):
7777
27900
1084
1264
1156
1094
1155

I'm assuming 7777/udp needs to be forwarded, as does 27900/udp, but what else?

AFAIK, Epic has never responded this questions like this. I opened up ports 7700-50000 and the server still doesn't work from my home.

Surely someone from Epic can answer this question but so far the silence if deafening.
