merge 2 tcp connection in proxy

hii all
i'm trying to build a bot to online game
my problem is with the proxy
i redirect the game client ip to proxy and its work fine but when i connect the bot to the proxy it's create a new tcp connection to the server
so is there any way to make the proxy send/receive packets from both bot/client to server ???
ps:i tried to build a TCP proxy using autoit but it doesn't work
thx

You can't merge TCP connections or sockets. You'd need to get the connection socket of the game by hooking a WinSock function.
