Make sure LW's allowed thru your Windows firewall. That big connection problems thread has a link to firewall config instructions.
AFAIK, Qwest don't block p2p. Have you tried accessing that test page with another browser?
You could try changing ports. Within LW go tools > options > advanced > firewall config. On this page you'll see LW's listening port. Change it to 64049 > apply > ok.
Your modem has a firewall. If the modem supports UPnP,enable it & then choose the UPnP option on that same firewall config page where you changed port number. See if that helps.
If not, you could try port forwarding. Check the link below for instructions & don't forget the step of setting up a static IP, otherwise things won't work

Just remember that any ports forwarded have to be the same number as LW's listening port & ports allowed through a firewall. All numbers have to be the same.
