Yikes.
Let me help.
I'll edit with what you should have in those boxes.
Edit::
**NOTE** Start off with just trying each number, and if just that ONE number doesn't work, only then, and ONLY then, continue. For example, #1 might fix all your problems, but then #3 might mess them up again. SO just try a number, then check your server list. If it doesn't work, go on to the next. (Keeping the previous number completed, of course)
1: Check off the "Enabled Box" instead of the "Disabled" box.
2: Copy + paste the Source box to the next box next to it and change the last number to an 8 or 9.
3. Same as #2, but with the Destination box.
4. Check off the "Allow Paintball2" box, bottom left.
If ALL of that doesn't worlk, then try changing the "0" in 192.168.0.100 to a 1. (In all four boxes)
Hope this helps,
Brock.
