I have the same router as you. And after some hard brain use i found my problem 
You have to add your ArmA2 server as Virtual Server in your Advanced settings...
This is my settings. And it works.. my arma2 server are now public 
Advanced - Virtual Server
PHP Code:
Name Public Protocol Schedule
ArmA2 2306 UDP Always
IP Address Private Inbound Filter
your ARMA2 local IP 2306 17 Allow all
Start with those settings and let me know if you got any problems...
And please close/remove all the other ports you have open up (2300-2400,47624 ,53, 80, 88, 2302, 2304, 2305, 2306, 2074, 3074 ,28800-28900)
Cheers

I tried to join an online server with both CPU (took awhile to find a server!) but finally I had both connected in the same server, so it wasn't an IP thing.
Then I tried another test. Both computers connect to only about 10% of servers, but NOT THE SAME ONES! WTF! I have no idea how to fix or even what to try when nothing is consistent.
HELP HELP HELP. I really want to play!
