I'm trying to get hairpinning working on an RV016/RV042 (accessing internal machine with external IP address). Configuring 1-to-1 nat works, except that outbound traffic is then blocked for the target machine (okay for other machines). Turn off 1-to-1 nat and outbound traffic is allowed again on the target machine, but hairpinning stops working.
Thanks for any help anyone can give!
