        What information did you use to connection - I was never able to get this to work.

          @johnpoz:

          What information did you use to connection - I was never able to get this to work.

          • Log in to the client section of OpenVPN-AS as the user you want to use and download the "Yourself (autologin profile)" file.  If you don't have this, log into the admin panel and enable autologin for the user.

          • Open up client.ovpn in notepad or similar.

          • Copy the contents of the <ca></ca>block into a new CA cert in pfSense.

          • Copy the contents of the & blocks into a new cert in pfSense.

          • Create a new OpenVPN Client.

          • Fill out the server and & port as appropriate.

          • Uncheck "Automatically generate a shared TLS key" and copy the contents of the <tls-auth></tls-auth>block into the box that appears.

          • Pick the CA & Cert you created in steps 3 & 4.

          • Set the encryption algorithm to whatever you're using in OpenVPN-AS.  The default is BF-CBC unless you changed it.

          • Check the box for Compression if you enabled it in OpenVPN-AS.

          • Save the OpenVPN Client connection and verify that the tunnel comes up.

          • Create a new interface and assign the VPN tunnel to it.

          • Edit the interface, enable it, and make sure that None is set for IPv4 Configuration Type.

          • Add an outbound NAT rule for your new interface.

          • Assign the new gateway to whatever firewall rules you want to force through the VPN tunnel.

          I can break anything.

            I was only putting in the .. I will be testing this tonight and then doing a guide for the docs!!  Thanks!!!

              Sweet bing bang zoom and routing traffic through the vpn.. But kind of eye sore is that its creating a VPNV6 Gateway

              I have no desire to route any sort of ipv6 traffic via this vpn connection.  On the interface its set for none on ipv6, do you happen to know how to get it not to create this gateway??

                No, I have no idea how to get rid of it. I've got a bunch of those on my systems.

                  I am having issues connecting to my OpenVPN-AS

                  I did follow instructions, however it's not working for me, and i am unsure what i am doing wrong.

                  Error logs shows this:

                    And without you posting your configuration, either would we ;) Nor even the full log..

                    So I just fired this up per the instructions in this page, I really should finish that guide I started..  Click click…  I tell it not to pull the routes for my testing of this, and if your going to want to do policy based routing, etc.  no reason to pull that you default route, etc..

                      I apologize, you are right.

                      I will get more details tonight - screenshots from both OpenVPN AS and pFsense's OpenVPN Client section.

                      Big thanks for responding and i apologize again!

                      P.s.
                      Thanks for screenshot.

                          See where you have no compress preference.. But most likely as server is doing compression, see the warning.. That will cause issue..  Set the drop down to do compression like mine enabled with adaptive

                              it is see your warning… I would have to log into one of mine and look to where/if you can turn it off.

                                Thank you!

                                That worked, it connected to OpenVPN-AS.

                                Would you mind if i ask another question - i am trying to accomplish something and i am not 100% it can be accomplished / done.

                                Big thanks again!

                                    Thank you!

                                    I have 4 PC's , 2 Laptop's , 2 Smart TV's in my  "home network".

                                    I have Wi-Fi R7000 Router in AP mode.

                                    I would like to have only 2 Smart TV's using OpenVPN's AS IP (so, 2 local IPs - i already have those IPs assigned as Static IPs in pfSense).

                                    Is this possible? Would you mind helping with this?

                                    Big thanks,
                                    damir

                                      Sure this is a simple policy route.. Assign your vpn connection to an interface.  Set this up as gateway, then create a rule in your lan that says hey if this IP or IPs going anywhere go out the vpn connection.

                                      I am about ready to leave work, and much easier to setup and show screen shots when home vs remote..  Will post some screen shots how to do when I get home.

                                          Ok here you go..  So make you assign your vpnclient to an interface - don't give it an IP, then create a gateway using that interface (do not set it default).  You can disable the _v6 interface it creates.

                                          Make sure you have a nat to this interface in your outbound nats to your network range.

                                          Then create a rule that says hey your source IP or IPs when NOT going to your local networks.. That is what the ! is in the rule and I use an alias that has my local networks in it and tell it to use the gateway.. Now when that source IP or IPs is going to anything other than your local networks that rule will trigger and send that traffic down your vpn client tunnel.  See attached images - so my normal workstation has my normal 24. IP on public - but when I use a vm that is 192.168.9.230 it goes down the tunnel.

                                          Make sure you devices you want to go down the tunnel use the dns you want to use and you should be set.  Also you might want to make sure you don't get any routes from the vpn client connection, see my above post showing my client config - see how I have checked block routes checked..  You don't want pfsense getting routes you may not want.. you just want to send the traffic down the tunnel based on your policy.  Quite often openvpnas is set to default route.. So pfsense could get a default route pointing down the tunnel, etc..

                                            I am having issues figuring out how to set getway for firewall rule on specific IP

                                            I go to:
                                            https://192.168.1.1/firewall_rules.php?if=lan

                                            it looks like:

                                            when i go to edit it, it looks like:

                                            i think i am on correct page?

                                            sorry for bothering you so much with this.

                                            thanks
