removing hardware firewall in router

Ok, the port for RF Demo is 7755, right?! I opened that port, just like everyone else who can't get it to work, and still no go. If it's so easy, then tell me how. I'm dying to know...
Obviously either RF demo is using another port as well, or a UDP port, or a non-TCP/IP protocol, BUT WHICH?! Becuase it doesn't appear to be published. I have a port list of ALL the TCp and UDP ports and failing opening all, or trying one by one, just opening the port 7755 which rf demo uses doesn't fix it. Please enlighten me o' learned one :P

I won't hold my breath...
