      Using multi-wan or other policy routing by chance?

      If so, the traffic is probably hitting a rule with a gateway and getting shoved out a WAN instead of following the firewall's routing table.

      Add a rule at the top of the list with a destination of the VPN network(s) that has no gateway set.

      EDIT: I didn't see your attachment there earlier, so I see you aren't. Though checking the system's routing table on both sites is a good idea.

        Thanks,

        I think the routing tables looks fine. The attached is from the client, and the server looks the same (but reverse of course :) )

          Could this be related to iroutes?

            If you don't have iroutes setup (or setup properly) then yes it can be related to iroutes.

              i do have an iroute on the server with just the CN of the client and the following line:

              iroute 192.168.10.0 255.255.255.0;

                You might be hitting this:

                http://redmine.pfsense.org/issues/1417

                Try adding this to your custom options:

                client-config-dir /var/etc/openvpn-csc;

                  Yes, that was probably it. Thanks!

                  I think I have some other problems with my configuration but it looks much better now!

                  Thanks a lot for your help.

                    Packet captures tells me everything works fine on the server side, but remote side doesn't route between openvpn and lan interface if source is from behind serverโ€ฆ

                    Do I need iroutes on the client side as well?

                      No, iroutes only go on the server side. Clients just have route statements. Servers need both route and iroute. Check the doc wiki, search for iroute, there is a troubleshooting doc.

                        Thats what i thought.

                        Checked the docs and I have it set up exacly like described. Acts just like the iroute problem on the server though.

                        I had to set mode server; could that cause these types of problems?

                          I think I've got this sorted for sure, it works for me in a Peer-to-Peer (SSL/TLS) setup with iroutes between two VM networks.

                          https://rcs.pfsense.org/projects/pfsense/repos/mainline/commits/0cc5ab42269a5aa1588ac2f862b0201917569ada

                          Either try that change or wait for the next new snapshot and then try it again.

                            Had to wait a while to be able to upgrade the remote side, but I am happy to say that it is working just fine after updating to the latest snapshot on both sides.

                            Thanks for your help jimp!
