I don't use Vista, but here goes...

If you're using McAfee's firewall, check that Vista's firewall is off: Start > Control Panel > Security > Windows firewall. If it's on then turn it off... 2 software firewalls running together will conflict with each other. Stick with the McAfee firewall. Try removing all LW rules from the firewall & then add them from scratch.

Your port test didn't work, which isn't a good sign... LW's default port is blocked by something. Maybe your ISP?
If you search on Google, there's conflicting info about QWest blocking ports. Most people say they're not. But they may be throttling p2p (file sharing) bandwidth. Changing port numbers is an easy thing to try in any case ...

In LW go tools > options > advanced > Listening Ports. Change LW's listening port to 65000 (or you can try any port in the range of 49152 - 65535). Check to see whether the Use Universal Plug & Play button is checked. If not, check that button > click ok.

Check whether UPnP is enabled within your router: Log into your router by opening a browser & typing 192.168.0.1 into the address bar. Once you're logged into your router, click on Setup > click on Advanced Setup (left side) > click on UPnP (left side). If UPnP is already enabled then you can just close out of the router setup. If UPnP isn't enabled then check the button to use UPnP > click on Save & Restart (left side).

There are also other fixes to try here: If LW 5 Will Not Connect

Let us know if none of that helps & we can give you instructions for port forwarding.
