I have a multi-site VPN currently running with pfSense boxes and currently using OpenVPN. However I can change the OS and VPN type if need be.

The main router has a 10.13.0.0/16 subnet and a series of public IPs

For example, a branch has a 10.12.1.0/24 subnet

How can I port forward NAT traffic on a public IP of the main router to a server behind the NAT of the second? So for instance port 95 on a public IP assigned to the main router forwards to 10.12.1.102 on the other router.

Is this even possible? Currently my setup works great but only for intertnal traffic
