1. Does LW show the brick wall in front of the globe?

2. Do the bug report test I gave earlier. Is yours true or false? If false, then you have a firewall issue.

If the problem is not your computer software firewall, then it will probably be your modem or router. Most high speed modems have NAT firewalls. UPnP can open incoming ports for LW. However if your device does not have UPnP ability, then you'd need to manually open the port using port forwarding. Port forwarding requires a static ip (without a static ip, manual port forwarding won't work!)

BTW what firewall do you have on your computer & which operating system are you using?

What modem & or router are you using (what's its brand name & model version)?
