D-link WBR-2310 Router

I have been uable to forward ports 5198 to 5200,using this router(or any ports for that matter)to be able to use the Echolink Program for Ham Radio, I have used portforward.com for instructions, have done this on my old Linksys router WRT54G and everything worked well, not so with the 2310. I have DSL from Embarq, using a SP-660 DSL Modem, set up a static IP on my computer as per D-link instructions. Nothing works Any Thoughts as to how to solve this. Thanks
