      You use static routes like this form the command line.

      jbusch@erl:~$ show configuration commands protocols
      set protocols static interface-route 10.254.101.0/24 next-hop-interface vtun101
      set protocols static interface-route 10.254.102.0/24 next-hop-interface vtun102
      set protocols static interface-route 10.254.104.0/24 next-hop-interface vtun104
      set protocols static interface-route 10.254.105.0/24 next-hop-interface vtun105
      set protocols static interface-route 10.254.201.0/24 next-hop-interface vtun101
      set protocols static interface-route 10.254.202.0/24 next-hop-interface vtun102
      set protocols static interface-route 10.254.204.0/24 next-hop-interface vtun104
      set protocols static interface-route 10.254.205.0/24 next-hop-interface vtun105

        That's what I thought, and I have: (the local side is 192.168.1.254/24 and the far side is 192.168.2.253/23)
        protocols {
        static {
        interface-route 192.168.2.0/23 {
        next-hop-interface vtun0 {
        description "route to other side"
        distance 1
        }
        }
        }
        }

          My interfaces look like this on both sides:
          0_1467728712057_PAL-interfaces.png
          in that both have traffic on the Tx side of the tunnel, but nothing on the receive.

            You did not specify, but I assume that you have the opposite on the other side?

              What does your OpenVPN config look like on both sides?

                      I see one of the peers is using another IP... but I don't know how to change that.

                        Ok, so the x.x.x.218 IP is the WAN IP of the opposite reouter, instead of using the openvpn IP.

                            if i got the static routing protocols backwards, just reverse them. They should point to the LAN on the opposite router.

                            That is the last line prior to each commit.

                              Ok, so it all looks good. What would be the best test?

                                  I can't ping LAN IP's on the opposite side...

                                  Well if the tunnel is up, you should.

                                  I intentionally deleted the OpenVPN interfaces just to make sure there were no firewall policies hanging around on them.

                                  So start with the basic. is the tunnel actually up and able to pass traffic.

                                  From router 1 ping the IP on the other end of the OpenVP tunnel.

                                  ping 10.99.99.1 or ping 10.99.99.2 whichever is on the opposite side

                                  nothing but the routers will be able to use these addresses. they are only for pinning up the OpenVPN tunnel

                                      Yeah, no dice.

                                      Then the tunnel is not up. Something else was done wrong.

                                        open up 2 ssh sessions to one of the routers.

                                        Do not go into config mode.

                                        in one, watch the log, show log tail

                                        in the other window, reset the OpenVPN connection reset openvpn interface vtun0

                                        see if anything in the log is useful

                                          Out of curiosity is there a reason to use OpenVPN over IPSEC?
