      If I disable the floating rules and ping 8.8.8.8 instead of getting "destination host unreachable" it says "request timed out" on both machines. So that doesn't seem to be the problem.

        This means that DO NOT NAT is applied. So packets are not dropped. But still lurking. Keep Floating disabled for now. Try turning off do not nat rules. ( keep in mind they are applied top down.) If one doesnt apply next one will catch it ;)

          OK so (Note: EU Do NOT NAT is on top)

          TEST 1:
          ALL floating rules disabled -> USA DO NOT NAT unchecked -> USA VPN disabled = USA machines can ping / EU machine will not ping

          TEST 2:
          ALL floating rules disabled -> USA DO NOT NAT unchecked -> EU VPN disabled = USA machines can ping / EU machine will not ping

          TEST 3:
          ALL floating rules disabled -> EU DO NOT NAT unchecked -> EU VPN disabled = USA machines can ping / EU machine will not ping

          TEST 4:
          ALL floating rules disabled -> EU DO NOT NAT unchecked -> USA VPN disabled = USA machines can ping / EU machine can ping

          TEST 5:
          ALL floating rules disabled -> ALL DO NOT NAT unchecked -> USA VPN disabled = USA machines can ping / EU machine can ping

            Figured it out. The problems was that under Firewall -> Rules -> Lan, proto was set to "TCP" on both VPN's, I changed proto to "Any" and now if one vpn goes down the other one still works.

              How to use Policy Based Routing and Multi VPN

              • I Followed this guide http://www.komodosteve.com/archives/232

              • NOTES: I used the same server port for both VPN's

              • NOTES: I added the following commands into Advanced Config (When pfSense first boots it loads VPN_IP_#1 but if the client gets restarted it will randomly pick of the the 3 VPN_IP's

              • SCREENSHOT: OpenVPN Client 1

              • SCREENSHOT: OpenVPN Client 2

              remote_VPN IP_#1 Port#;
              remote VPN_IP_#2 Port#;
              remote VPN_IP_#3 Port#;
              remote-random;

              • SCREENSHOT: System Gateways

              • This is where you will setup two aliases for the USA VPN's and EU VPN's

              • Make sure you have static IP address for the machines

              • I made 3 rules (1 that redircts the EU vpn through the EU gateway, 1 that redirects the US vpn through the US gateway, and 1 that selects every other IP address not specified in aliases and sends it to the defualt WAN gateway)

              • Proto: ANY, Source: Alias, Gateway: VPN

              • SCREENSHOT: Firewall Rules 1

              • SCREENSHOT: Firewall Rules 2

              • First delete all rules

              • Select "Automatic outbound NAT rule generation" and click save

              • Select "Manual Outbound NAT rule generation" and click save

              • This should auto created any rules needed for the VPN's

              • Now create a rule that will stop traffic if the VPN is down

              • Click "Do not NAT", Interface "WAN", Protocol "any", Source "Alias"

              • MAKE SURE you move the rule to the top of the list as pfsense carries out rules from top down

              • SCREENSHOT: Firewall NAT Outbound 1

              • SCREENSHOT: Firewall NAT Outbound 2

              • Action "Block", Interface "WAN", Direction "any", Protocol "any", Source "alias"

              • SCREENSHOT: Firewall Rules Floating 1

              • SCREENSHOT: Firewall Rules Floating 2

              • This along with with #5  will block your machine from going to internet

                                  Lol yes I think so, remember rules go top down.
                                  So if rule us caught before bottom one that one is executed.

                                  ie.
                                  1. If source…. EU, DESTINATION = google.com then US
                                  2. if source EU, DESTINATION * then EU

                                  so #1 will be executed. you can also use ! in front of ip etc..... which will mean if not this then that..

                                  The only issue is i think domain names wont work... and you may have to use ip address instead.

                                        The problem is still there even after making all the changes. The annoying thing is that when the US VPN is in this reconnecting process, it kills all other internet connection even the EU VPN and normal WAN, however; if all the VPN's are up and running normally and then I disable the USA VPN, the EU VPN and normal WAN work just fine… My entire VPN client setup (with pictures) is shown on page 3. Does anyone have any ideas?

                                          What if EU goes down does it bring down us one?

                                            If I disable the EU VPN the US VPN works.
