      Hello -

      I have a network of 2 pfsense routers in 2 locations.

      everything is connected over ipsec and working great, everything can ping everything and traffic flows and its awesome.

      pfsense1 is 10.47.0.0/16
      pfsense2 is 10.72.0.0/16

      here is my challenge:

      I have a /24 inside the pfsense1 network of 10.47.5.0/24

      I need that specific /24 to ONLY route through the network of pfsense2, that is to say the traffic from that 24 enters and exits from the wan of pfsense2.

      I have looked elsewhere and seen example of how to do this using openvpn, where route statements can be used to direct traffic using the openvpn gateway.

      unfortunately, i do not see an ipsec gateway declared in my setup, so I cannot do that despite the fact that everything is working (and has been working well) for many months.

      any guidance would be greatly appreciated, and i am standing by to upload any configs from any router.

      all the best

        That's because you cannot policy route IPsec like you can OpenVPN.

        You might be able to use a phase 2 of 10.47.5.0/24 <-> 0.0.0.0/0 with the reciprocal on the other side, but OpenVPN is a lot more flexible in this regard.
