solve rout rdp problem - repost 2

I need a code to "route" my rdp connections. I tried to create a simple program that listens on some port, and connects to a remote rdp port (3389 opn some pc), and just passes the packets from each end to the other. It works for most tcp connections, and it works if I use clients other than mstsc (such as royal ts), and it works for vnc and pca. It does not work for mstsc. I need to understand why, and make a program that does route it. ================================================================ The problem is not that the program doesnt pass the packets right, it does. Perhaps the mstsc client checks the local ip, I dont know what. Just for reference, here is the 2 minutes code in python that I used: import socket import select def route(srchost, dsthost): ls = [login to view URL]() [login to view URL](srchost) [login to view URL](20) ss, inhost = [login to view URL]() ds = [login to view URL]() [login to view URL](dsthost) while True: rlist, wlist, xlist = [login to view URL]([ss, ds], [], []) if ss in rlist: [login to view URL]([login to view URL](1024)) if ds in rlist: [login to view URL]([login to view URL](1024)) Sincerely, Shahar Papini
