Hi there. I have a basic setup (default settings) + a few blocks on 123 and 135 (both work great). But no matter how much I block ports 21-23, 1720 and other that are detected as "open" on grc.com (ShieldsUP) or PC flank test, they all remain this way - open! So my question is: How do I make blocks on port 21,22,23 so they are not "open" but closed or stealthed? I will then use the same way for all other ports left "open" by GhostWall. Thanks!
