      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?

              This is not my setup, so I have no idea on their reasons.
              I use OpenVPN when connecting a home router into an office for site to site because OpenVPN has long worked better (for me) with dynamic IP addresses.
              I will use IPSEC for static assigned offices because you get more throughput when offloading is enabled.

                I don't see any reason we couldn't/shouldn't use IPSEC.

                  Run the delete commands from before, then go into the GUI and setup IPSEC.

                  delete blah blah
commit
save
exit

                  go to GUI.

                    well, I can ping from site B to site A now, so that's good. Both sides said the configuration was applied successfully. I'm trying to ping router-to-router and it only works one way. In advanced options, the NAT exclusion is set and applied.

                      My bad. I didn't realize that IMCP response was disabled on the site B router. I can ping across the tunnel to servers on the site B LAN. Success!

                      Huge thanks to @JaredBusch for all of your help today!

                        Big thanks to @JaredBusch I was in a hurry to leave for a speaking engagement and had to hand off to @art_of_shred . It turns out part of the problem was that some of the servers on the far side had a persistent route set up so that even when we changed the gateway address from the Meraki to the EdgeRouter, they were still hitting the Meraki. Now that it's off hours I ripping through 19 servers to make sure the gateway is correct and there are no persistent routes configured that will mess things up.

                          @Mike-Davis Assume everything dumb that could be done has been done down there. What a mess.
