Hi Ralph...
You have done the right thing for the manual port forward box and the listening port box, the number 51279 should be fine...
Here is the static IP set up instructions, this part is very important, if this doesn't go right it wont work...
PortForward.com - Free Help Setting up Your Router or Firewall
When you type in 192.168.1.254 into the address bar of your browser you should get your log in page to your modem/router, you don't need to save it...
If you continue to have problems with the log in, contact your ISP and ask them for the log in details....
ps...I'm actually WW not birdy...
