Test Worked
One other computer is using my network. My computer is the host.
Have used LW for years.
Yes, firewall was detected.

1) The only software firewall is the one supplied with windows XP. It is disabled.

2) UPNP is enabled on the router, port forwarding had no effect.

3) The second computer, which also uses the same version of LW, goes through my router and modem as well, and has no problem with its connection, therefore leading me to believe that this is not a problem with the configuration of the router/modem.

Apparently LW is detecting a firewall that either doesn't exist, or resides with the router/modem and yet allows the secondary computer to connect despite mine being the host. I'm no expert, but one would think that if the problem lay within the m/r, it would affect both computers, not just mine.

Any suggestions or further information needed?
