Dlink has emulator for your router on their site, I just pulled this up. Navigate to the filters page of your router, add your two computers MAC. Open windows command prompt, type "ipconfig /all" and it will list all MAC address's of adapters. Add these to filters in Dlink.

I was worried I'd have to add a couple of hubs but that was not necessary. Thanks again! ;-)
