Can you port forward with double NAT?
To check for double NAT on your network, log into your router and look up the IP address of its WAN port. One way to compensate for double NAT is to set up separate port forwarding rules on each device so that incoming traffic is shepherded through both layers of NAT.

Do you have to use NAT to use pfSense?
You simply don’t need to use NAT to route or use the firewall. You can use the firewall to disallow users from accessing the ISP services, and you get the boot services that work on pfSense. This should solve the double-NAT port forwarding problem.
When does a port forward rule exist in pfSense?
When a port forward rule exists, pfSense will allow any traffic matching corresponding firewall rules. The firewall does not know the difference between a packet with a malicious payload and one that is benign.
When does port forward take precedence over 1 : 1 Nat?
Port forwards also take precedence over 1:1 NAT. If a port forward is defined on one external IP address forwarding a port to a host, and a 1:1 NAT entry is also defined on the same external IP address forwarding everything into a different host, then the port forward remains active and continues forwarding to the original host.
