Did the port test work? Who is your ISP?

You could try enabling UPnP within the modem, then choose the 'use UPnP' option within LW's tools > options > firewall config. Apply to save a change.

If that doesn't work, there's always port forwarding. Don't forget to set up a static IP address first (there are instructions at the link below). Once you've set up port forwarding, choose the 'manual port forwarding' option on the same LW options page as for using UPnP. Make sure you enter the same port number as LW's listening port. Instructions for port forwarding are below.

*If your port test did not work, post back before trying these other things.
