      Route command if vpn active:

      Destination    Gateway        Genmask        Flags Metric Ref    Use Iface
      192.168.78.0    *                    255.255.255.0  U    0      0        0 tap0
      192.168.3.0    *                    255.255.255.0  U    1      0        0 eth0
      192.168.3.0    *                    255.255.255.0  U    2      0        0 wlan0
      192.168.0.0    192.168.78.1    255.255.254.0  UG    0      0        0 tap0
      link-local      *                          255.255.0.0    U    1000  0        0 eth0
      default        192.168.3.1          0.0.0.0        UG    0      0        0 eth0

      192.168.78.x is my ipsec mobile client range configured in PFsense.
      192.168.0.x/23 is my remote subnet.
      192.168.3.x is my local network (in this instance at home).

      Looks good to me??
      Anyone some tips?

            Yes, you must have firewall rules in the VPN (racoon or openVPN) before it allows traffic to pass over the VPN.

              I have configured my firewall rules correctly, since traffic can go trough the tunnel on a windows client.

                Do you have iptables enabled on the linux system?

                      If you traceroute from the linux system to something behind the remote firewall, where does it hang in the path?

                          Not sure … I tested my Shew in Linux and it worked. Though mine it not using a tunnel interface. I have use existing adapter and I have a policy of the remote network.
