      Hi,
      I am trying to set up multiple ProtonVPN wireguard gateways for load balancing and failover. Proton always uses 10.2.0.2/32 for all their VPN servers. This causes issues as pfSense does not like multiple gateways with the same IP address.

      Is there a way to get around this limitation? I thought of using 1:1 NAT, but the NATing occurs after the traffic reaches the interface, which means the IP on the interface does not change.

      I have searched the web, and most people state it cannot be done. I find this hard to believe as I am sure this has a use case (eg. corporate mergers).

      Thanks in advance.

        I found the solution:

        ProtonVPN allows alternate gateways following the format: 10.x.0.2/32
        I have tested 2 through 9 (10.2.0.2/32, 10.3.0.2/32, ... 10.9.0.2/32) and they work.
