Like I said before: My specific problem is that one user is able to use LW just fine while the other is unable to connect.

Just check that you're using a different port to connect on each computer. Tools > options > advanced > firewall config will show you LW's listening port.

The router has a firewall, which is probably why you're seeing the firewall icon, even on the computer that can connect. Try port forwarding. It might fix your connection problem for one computer & firewall problem for both. There are instructions here

If you want to set up port forwarding for both computers, you'll need to set up a different static IP address for each computer. Also, forward a different port for each computer. LW's listening port, port forwarded & any specific port number allowed thru a software firewall must be the same number.

Just double check your McAfee configuration for both computers.

Thanks for your help. The connection problem is one the same PC between two users.
