I see, so the only difference between your cases is the direction of the network connection. Would you mind trying the P2P software linked below in my signature? It runs both as server and client... so you be able test both directions simultaneously (computer A connecting B, computer B connecting A). In case a connection fails, is there a different error message than "timeout"? One more thought. If one of the computer has multiple network adapters (run 'ipconfig' in console window), you can try connecting different IP addresses. If the VPN connection does absolutely not work for you, check with your network admin before you try to circumvent possible filters. ;) /M Webchat in Europe :java: Now with 26% more Twitter modified on Thursday, March 18, 2010 5:48 PM

As I indicated, those three functions do not have the same signature as the biasFn type. "Ideas are a dime a dozen. People who put them into action are priceless." - Unknown
