The setup as described in your link isn't really hairpin NAT.
It is NAT masking. (You translate the address inbetween the 2 routers with a NAT policy engine, that translates the internal IP back into the public one).

Now my only question is, do you have 2 of these routers behind eachother in your current setup ?

If not, the fix is simple :

1. Do I need to manually configure hairpin NAT when using port-forwarding?
No, the port-forwarding wizard includes a checkbox that can automatically configure hairpin NAT for you.

If true, you will need to follow that guide to the letter, but put your own IP's in, and obviously the ports you use for opensim.
