tappit, if you're using XP then make sure you've turned off the XP firewall. It will conflict with Norton & cause problems. Just double check that LW's listening port is still 6346 (my port has changed by itself before). Your model isn't listed at the portforward site either. Does the router support UPnP? If it does then enable it within the router & tick within LW's options > advanced > firewall config then Apply. No guarantees but it's worth a try!
