The number you have highlighted in red is the port number that LW is using.

Tools...options...advanced...firewall config

I'm not sure if this answers your question.

I got it. Thanks for the info. My next problem is that I can browse some hosts using Direct Connect but mine is not available to them. I am using LW Pro but above the Direct Connect Box, it is mentioned like this: Your computer is behind a firewall or router and cannot receive direct connections. I put off my Windows Firewall already but to no avail. Any suggestion on how to enable receiving direct connections? I am using Speedtouch ADSL Modem with four ports and one wireless. At present, only one PC is connected using one port.
