      The captures are running on the ovpn interfaces. Should i have been capturing on another interface?

      As far as ping LAN interface - no, i can't reach it from one side to another. However if the client is on the same side, pfsense's LAN int responds to pings just fine.

        Having said that, it looks like I can ping clients on Side A if i'm sitting on the console of pfsenseB.....

        however it doesn't work the opposite way, i.e. if i'm on the console of pfsenseA, i can't reach anything on side B.

          It doesn't make any sense that you are seeing traffic exit the VPN at A but it does not arrive in a capture on openvpn at B.

            Could it have something to do with the fact that pfsenseB WAN IP is on 10.x.x.x subnet?

              Not unless it's within or conflicting somehow eith the others. And you'd still see the packets in the capture on the OpenVPN.

                hmm ok, what else can you suggest I try? I do have multiple ovpn instances on SideA, but i can't imagine that would conflict with any of them since they're running on different ports....

                  It's not about ports but addresses/networks. They all need to be unique.

                        Don't know. I asked for some files in chat. Did you upload those?

                              guess not, no problem. thanks for giving it a shot, i do appreciate it.

                              Just as an update... I thought... well maybe it's one of the packages that's interfering with the traffic... so I've set up a completely vanilla lab on the vmware workstation. The only package loaded on both sides is open-vm-tools....

                              Same exact results.... so it makes me think i'm doing something wrong. I'll keep picking at it....

                              Any other suggestions are welcome.

                                I kind of gave up on the openvpn and went with IPsec... seemed to work as expected on the first try.
