      Are there any known issues with tunnels involving /23 networks? When I try to set one up between two pfsense boxes, Phase 1 negotiation completes successfully but Phase 2 just spins its wheels.

        Shouldn't be any problems, no different than any other subnet.

        As long as the phase 2 info matches exactly, it should work. Anything in the IPsec logs on either side about it?

          Thanks, glad to know it's expected to work, at least. Logs just show the usual …

          racoon: ERROR: failed to pre-process packet.
            racoon: ERROR: failed to get sainfo.

          .. but if I adjust masks on both sides to /24 then the tunnel comes up right away.

          I'll try debug mode later today.

            Oops! Just needed to make a simple Phase 2 setting adjustment, of course.

            the local pfSense LAN IP address is …

            ... so initially i had set the remote tunnel to connect to ...
            x.x.2.0/23

            ... but upon reviewing racoon debug output, I realized that for a /23 network it should actually be ...
            x.x.1.0/23

              That would do it. :-)
