How is it that the client can receive a message through the firewall if it can't establish a download? Most home (DSL/Cable) firewalls block all incoming ports unless the initial connect was established from inside the firewall.

I have yet to see even one 192.168.x.x clients ever work for me. Limewire should be picking up on the firewall IP address, not the client IP address. Hotline does it this way and it works great.
