UT Proxy Server

(1/2) > >>

Xecutioner:
Haven't done much with this one and the proxy it's self is not my code, I've just adapted it and added optional logging.  It can be used as a base to modify or log packets in any game really.

The packets sent are ridiculous and there is very little information on how they work.  Basically each packet has multiple sets of data inside to decrease the size of the packets sent.

I think this is a simply connect to a proxy to change IP to have a species as anti ban, I have not read the source code but from the title i conclude that serve for this....
