What models of modem & router do you use? Instructions (or links to) can be found here: http://www.gnutellaforums.com/showth...threadid=25119 If you can provide further details perhaps we can help you thru the steps. Within LW you'd need to enter the port you'er using for LW into BOTH the Port option & Firewall port option & tick the Force IP option. These can be found under LW's menu Tools-Options-Advanced & both the Port & Firewall options.
