I've tried the above, and still have no luck. I'm using a VSAT (Satellite) connection and everything WAS originally working fine and now it's not. I couldn't pull up a web page until I adjusted the proxy in IE and FF. Now I can pull up a web page...but my FTP clients (WS-FTP and FileZilla) keep timing out. (They USED to work) I've tried passive, I've tried specifying the port but to no avail. My Yahoo/MSN/Skype/VOIPBuster won't connect. From time to time MSN will connect momentarily but will never send messages and simple drops out. Skype used to work and now it won't since I've been playing with settings. This is driving me mental as it has crippled my ability to work. After reading your forum I checked to notice windows update has indeed installed the firewall. Even when I switch it off, I still can't connect to any of my servers...and chat clients simply won't log on. Any ideas?
