      I have the exact same issue. Did you ever figure it out?

        no solution, gave up, waiting for 2.1 to try again

        is documentation outdated or is there something inherently wrong with a single openvpn server listening on all interfaces?
        this suggests running 2 openvpn servers http://doc.pfsense.org/index.php/Multi-WAN_OpenVPN

          there is no reason why it wouldn't work … i currently have it working on multiple sites.

            It seems it only works on whichever of the two WANs the 'default' gateway at the time as shows under diagnostic>routes

            What can i do about this to be able to connect to either?

              tried something random,

              got non-default WAN2 working by switching OpenVPN to tcp mode,
              am i really the only one to ever come across this?
              tcp isn't ideal, is there a workaround to be able to use udp?

                Since you mention a different behavior between TCP and UDP, have you by any chance enabled NAT reflection for port forwards ? (under System -> Advanced -> Firewall & NAT)

                  No, it's disabled (default)

                  ok. this http://forum.pfsense.org/index.php/topic,8297.msg46717.html seems identical,
                  i tried this as per their suggestion, didn't help.

                  pf wiki http://doc.pfsense.org/index.php/Multi-WAN_OpenVPN
                  mentions 'udp caveats' at the top, and it suggests running 2 vpn server which i tried

                  to recap:
                  single openvpn server with 'any' for interface and 'tcp' allows me to connect from either WAN,
                  'udp' only works on 'default gateway' which is the problem

                    Well, then perhaps heper could share the way he configured it.

                      Hi all,

                      I used the links from themisa to help configure multi-wan OpenVPN for a non pf-sense router, but what was missing is that in addition to adding a 'local $IP' line to the duplicated config, you need to change the subnet for for VPN connections, having the DHCP address pools separated, but on the same subnet was not sufficient.

                      Hope that helps.

                        'udp' only works on 'default gateway' which is the problem

                        add to advanced options of openvpn client:
                        local 127.0.0.1;lport 0
                        Set "Interface" to any real interface, but NOT "any" (otherwise OpenVPN will not start).
                        In Gateway groups add group what suits your need (WAN as Tier 1, Second WAN as Tier 2 in your case);
                        in Rules add floating rule with following settings:
                        Quick: Enabled
                        Interface: select both WAN interfaces
                        direction: out
                        Proto: TCP/UDP or plain TCP
                        Source: Any
                        Destination: IP of OpenVPN server to whom you connecting
                        Dest port range: add your ports
                        Gateway: Choose previously created Gateway group.

                        Should work (although without failback)

                          I have same issue.
                          On my OVPN server, i can have either of the vpn connections up if the other one is down. The log produces this:

                          Oct 5 14:42:24 php: /status_interfaces.php: Starting 3gstats.php on device '' for interface 'wan'
                          Oct 5 14:42:29 check_reload_status: Reloading filter
                          Oct 5 14:42:32 php: : Gateways status could not be determined, considering all as up/active.
                          Oct 5 14:42:34 php: : Resyncing OpenVPN instances for interface WAN.
                          Oct 5 14:42:34 kernel: ovpns1: link state changed to UP
                          Oct 5 14:42:34 kernel: ifa_add_loopback_route: insertion failed
                          Oct 5 14:42:34 kernel: ovpns1: link state changed to DOWN

                          If ovpns1 is up then the log changes to ovpns2: if_add_loopaback_route: insertion failed etc.
