If you're using LW5, there's no firewall icon. In LW go tools > advanced tools...there you'll see whether you're behind a firewall or not.

YES, THE IMAGE IS THERE.

17. Has anything in your setup changed recently? Have you updated your version of LW or Java? Have you added any new software or new hardware? Have you updated any software? Have you moved house, changed internet plan or ISP etc etc?
NO.

I'm guessing UPnP worked for you previously? Whilst you might have been able to connect with LW 4.12, from memory it did not have a firewall indicator that something was not quite right. Just curious about the combination of airport & router. BTW why use the Gateway if you have the airport?

At least I presume you have LW set as an exception in OSX's firewall, or is it turned off? OSX Firewall settings for Tiger/Leopard

You should make sure you have a fresh gnutella.net file; see 2/3 way down this page: If LW 4 Will Not Connect (click on the blue link)

You could also check this method of excepting LW through your Gateway: Port Forwarding for the 2 Wire 2701HG-G

Since you are set to using UPnP for your airport (which will cause LW to use different ports each time connected), perhaps you should set a wide range of ports for LW to use via the Gateway. eg: 2000 - 65535. And do one rule for each of TCP & one for UDP, or both together if possible.
