Bump for more info - I've got a DLINK DI-624 - Ideally I'd like it to ONLY respond to two IP addresses - with no encryption (slower) - Is this possible? Help!
Open your Web browser and type “http://192.168.0.1” into the URL address box. Then press the Enter or Return key.
Type “admin” for the username and leave the password field blank (unless you've already set a password).
Click OK
Once you have logged in, the Home screen will appear.
Click Run Wizard
Do enable encryption. Your DI-624 is capable of much faster speeds than your internet connection, so the slow down due to encryption won't make a difference.
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.

Go here: https://www.grc.com/x/ne.dll?rh1dkyd2 and run all the tests.
I'm on a new Linksys, saw the article this AM, and found that the GRC tests gave me a clean bill of health.
Have ZoneAlarm and Norton ('04) installed, as well.
