I recently downloaded Limewire 5.4.6 to my new computer and have manually setup port forwarding via my wireless modem/router. I am able to achieve a connection with Limewire, however, I am unable to receive incoming UDP messages which in turn doesn't allow me to download any files.

I have turned ALL firewall programs (computer and modem/router) or setup exceptions for the Limewire program. Yet Limewire still says it is behind a firewall and unable to receive incoming UDP messages.

How do I fix this problem?
