modem + router portforwarding

i have a speedstream 5200 as a modem and a d-link 624 wireless g router.

now it seems like i set up the router by using port forward, but do i have to set up my modem using portfoward.com too for bitcomet to function?

and for a static ip address…do i have to use the ip address found using inconfig/all?

because, i cant see any other ip addresses that i can use?

You don’t/can’t portforward a modem.
