Thanks for your reply birdy,

Machine 2 has port forwarding enabled also - LW is showing as NOT firewalled.

I'm not sure about he chat options - it's a pretty much default LW installation, so if it's enabled by default then it may be enabled. Will give this a go on Monday when I get back in. And no, I wasn't trying to direct connect using the listening port, just the IP address, so thanks for that also.

I have played around with different ports on both machines, and do not think that will help, but will give it another go as last resort.

Thanks for your help.
