      @User1503:

      Can you outline in a few steps how to add an smtp to a rule for bypass?

      Post your LAN rules (or the rules for whatever interface is being used for forwarding to PIA.)

        Hmmm.  smtp.out.secureserver.net doesn't resolve.  You need to figure out where you need to send your outgoing mail.

          I just started using pfSense again after a long hiatus and can't get OpenVPN to work with PIA.  I had it working in an old version of pfSense but the options are different in v2.2 and I'm tearing my hair out.  Everything looks setup right but the gateway never stays up.

          After restarting the OpenVPN service the 'PIAVPN' Interface shows an IP address, but when I go to the Gateway status, the 'PIAVPN_VPNV4' gateway is always 'offline.'  According to the Gateway log:

          Feb 14 14:31:57 apinger: SIGHUP received, reloading configuration.
          Feb 14 14:31:57 apinger: alarm canceled (config reload): PIAVPN_VPNV4(10.100.4.5) *** down ***

          This repeats constantly.  I checked the OpenVPN logs:

          Nothing really stands out as problematic there…nothing else gets logged  until maybe 15 minutes later when I get this:

          Feb 14 14:48:59 openvpn[45424]: MANAGEMENT: Client disconnected

          Any ideas where I should be looking to resolve this?

          Thanks for the help!

            Looks like it's connecting to me.  What's not working?

            You probably can't ping the gateway directly.  Just turn off monitoring or find something else to use as a monitor IP.

              Thanks for the tutorial and it works….but does anybody know how to force OpenVPN to route traffic from only one vlan?  So, for example, I have the following interfaces:

              WAN
              LAN (10.0.1.0/24)
              Guest (10.0.2.0/24)
              OVPN (10.0.3.0/24)

              I want the LAN and Guest get routed through WAN.  How do I make only the clients on the OVPN interface use the OpenVPN tunnel?

              I've tried to limit the NAT to only the 10.0.3.0/24 net, but then the LAN (and probably Guest) wasn't routing any traffic out.  I also tried to setup some firewall rules to route the LAN to the WAN and make OVPN route it through the OpenVPN gateway, but nothing.

              Thanks!

                Thanks - the problem is that as soon as I adjust the LAN firewall rule to direct LAN traffic to the PIAVPN_VPN4 gateway, I lose all internet access.  I can't ping, traceroute, etc. anything outside my LAN.  I have outbound NAT rules setup for both WAN and PIAVPN gateways and firewall rules for each interface that are basically unrestricted:

                sorry for the crappy spacing in the output below

                  Umm.  First thing you should do is delete that WAN rule.  Do it now.  Don't delay.

                  Also delete the OpenVPN and PIAVPN rules.  Do it now.

                    Now that you've done that.  Show us your NAT rules.

                      Ha!!  Yeah, those non-LAN rules were NOT active (disabled) and are now deleted - otherwise that would kind of defeat the purpose of a firewall, right? :) The only firewall rules I have right now are:

                      The Outbound NAT Rules:

                      When I activate the "PIAVPN" version of these rules and the corresponding firewall rule, I lose all connectivity outside my LAN.

                      ***UPDATE: It's magically decided to start working now.  I have no idea what the problem was but it's good to go now.

                        You can leave the NAT rules active.  They mean nothing unless that interface is being used for egress.  They just have to be there if you're going from the source IP addresses out that interface.

                        Maybe PIA was having a problem?  Who knows.  Glad it's working and you don't have a pass any any rule on WAN.

                          One additional question: I can get the OpenVPN/PIA tunnel up and functioning, but when I come back after a while the Interface is down and the OpenVPN service needs to be restarted.  This is from the log:

                          Feb 14 23:26:43 openvpn[83612]: TLS: soft reset sec=0 bytes=494118/0 pkts=4201/0

                          Feb 14 23:26:43 openvpn[83612]: Exiting due to fatal error
                          Feb 14 23:26:43 openvpn[83612]: Closing TUN/TAP interface

                          Is this because I specified "auth-nocache"?  If so, shouldn't this option cause the information to be re-read from the file, not stdin?  I'll try and remove the -nocache option since, really, why should I mind having the login credentials saved in memory when it's OK to have them stored plaintext on disk…

                          Is it something else entirely?

                          Thanks,
                          Aaron

                            If you added auth-nocache outside of the tutorial, remove it.

                              Quick questions since I am still doing my research. If I wanted my VPN service (PIA) to use a different set of DNS servers, to prevent DNS leak, would it be possible? If so how would I go about setting this up? Or would pfsense as a whole have to use only one set of dns servers?

                              Sorry, still learning and haven't been able to get any hands on yet.

                              Thank you

                                great tutorial you guys have. I have a more complicated situation that I have been trying to get setup.

                                Having TWO openVPN client setup via PIA.

                                So the idea is this, based on IP range 192.168.0.2-192.168.0.20 it'll go to PIA USA west

                                The based on IP range 192.168.0.21-192.168.0.40 it'll go to PIA Canada

                                Then the remaining IP 192.168.0.41-192.168.0.254 will be on the WAN.

                                I've tried to follow the instructions before and just add a 2nd VPN client accordingly, but everything just default to the PIA USA West, is there anything I could be missing?

                                Hi there,

                                Not sure if you solved your problem, but if you haven't passed "route-nopull" as an advanced option to the OpenVPN client, that might be your problem.  I wanted to selectively send some of my LAN clients to VPN and others not, and had to pass this option as it stopped OpenVPN from generating a default (0.0.0.0) route in my routing tables.

                                Good luck!

                                Rob

                                  First a huge thanks to the OP for providing this.  Exactly what I was looking for.

                                  Second - and please bear with me as I'm new to pfSense - what is the best way to have ALL communication to the internet shut-off if for whatever reason the VPN becomes disconnected? Or maybe this is already going to occur because of the NAT rules defined?

                                  Thanks for clarification.

                                    I have found the best way to do this is to edit the firewall rules that policy route traffic over the VPN.  Configure them to add a mark like VPN_ONLY.

                                    Create an interface group for all your WAN interfaces.

                                    Create a floating rule on the wan interface group direction out.  Make it a Reject rule, Quick, matching any traffic with mark VPN_ONLY.

                                            Hey Derelict thanks for answering my other questiond.  My problem is..uh, I'm not the sharpest at learning; I can follow tutorials (and even wrote some for wireless) and what I need is another tutorial for setting up NAT (or LAN?) rules.  I followed this VPN tutorial and everything is running great!  But like other's have asked, I need to have 1,2 or maybe only 3 IP's (computers) use the VPN, and all other bypass the VPN and go straight to the local internet.  So the answer's I've read of 'create a Lan rule for xxx' are nice and I'm sure easy for some, but I don't know HOW to do that?  I made some LAN rules, but it blocked everything and so I just removed them.  Therefore, if you, or anyone, knows of another tutorial of 'How to create a rule for 1 IP to bypass the VPN' I sure would appreciate a link.  I can follow directions and be successful (driving, making coffee, buying groceries) but I don't know the 'how-to' of pfSense rules.  Thanks!
