AFAIK, you shouldn't need the tool from the portforward site...just follow their instructions.

Go through these static IP instructions, see if you can see your DNS server numbers.

If they're not there, you'll have to find out from AOL. You don't have to mention anything about static IP, they should just give you those numbers.
Once you've got all the info, set up the static IP & that's the number you have to enter into your router's config to port forward.

Then try these instructions for port forwarding

(there's no DG834G v3 listed, just DG834G...so just check that things look the same as the pages within your router).
At the end, don't forget that the listening port & manually porwarded port number have to be the same
