This release has not been tested by me. Besides some cosmetic changes in the code, it should fix an ugly bug affecting UProxy when used in Unix-like operating systrem (thanks to Manuel Moos who alerted me and suggested the patch).
If you have problems with the new version, let me know (see feedback section in this page). You can find the previous release here.
UProxy a proxy for UDP protocols. It is inspired by Vincent Amoroso's program udpproxy.
Initially UProxy has been designed to allow playing Unreal Tournament matches over Internet on computers connected by a LAN sharing a dial up connection, but it could be used to play other games (such as Quake) and by every program using a UDP protocol where clients don't have to bind a fixed port (not only games!).
The main reason why I did UProxy when udpproxy already exists, is because I tried to port udpproxy to Windows but it was so difficult that I decided to rewrite it from a scratch. As result, UProxy should compile (and work) under Windows, Linux and, probably, every OS supporting BSD sockets.
UProxy doesn't support all the features of udpproxy yet, even if it should not be difficult to add them. However UProxy is now pretty usable and I will wait before adding other features while I'm not sure I really need it.

My computer has the address 172.16.2.1 on my LAN. It is connected to internet by a dial up connection. If I want to allow computers on my LAN to access the an in Internet server having address 18.104.22.168 running Unreal Tournament on port 9999 I have to run the following command on my computer
uproxy 7777 22.214.171.124 9999
then other computers on the LAN have to use the address 172.16.2.1 as server (Unreal Tournament uses UDP port 7777 by default) to reach the Unreal Tournament server 126.96.36.199 on port 9999.
While running, UProxy prints bytes in/out statistics every 10 seconds.
When incomes a request from a new client a message is shown and 30 seconds after the last packet sent or received by the client the pseudo-connection is dropped and another message is shown.
