Well if Norton Firewall is permanently on & I had no control over it I'd dump it! Trash it. Better off using Win XP firewall & making exception for LW & Java. (If norton is on, you'll probably never be able to open a port for LW!)

Yes you probably have a modem router. As for which is safer, static or dynamic I'm not in the know, I use a mac.

You'll need to re-check your settings. You must port forward the same port number for both LW, the modem-router & any firewall. Make sure your settings have been 'saved'.
