Port Forwarding using Cable/Wireless

hope this is the right place to ask this…i was wondering if any of you more tech-savvy kf users could help me with this issue i am having…

im trying to set up port forwarding for azureus. i have broadband cable internet, and i am using the motorola sbg900 to connect to a wireless pci card in my pc.

the tutorial on port-forwarding.com says you need a static ip address, but when i set up a static ip the internet doesnt work…

is it possible to set up port forwarding with my configuration?
