After much tinkering around I finally got it to work.
I started to try to force AC to use certain ports by modifying the userpref file. I forced it to use port 9000 and it would log in (all this with a single client at this point), anything above port 9000 and it wouldn't connect, I tried 9001, 9002 etc.
Anyway, on to the fix. Originally I had my router set up to forward ports 9000-9015. Now I set it to forward ports 9000-9005. I added a second line to forward 9006-9015. In Dual Client I now force my first launch of AC to run port 9000, second one to run 9006. It worked!
Hope this helps.
When you say you added a second line, do you add another line with the same IP address?
