      Also in the CSO you must not use a /24 tunnel.
      How to set the tunnel, depends on the server topology. If it uses a /30 set also a /30 subnet in the CSO. If the server uses subnet topology set a single IP out of the tunnel.

      Also the "push route" in the advanced settings is superfluous. This is already done by the "Local Networks" field.

        The client is also a Pfsense so both are Pfsense (+ version).
        Ok I haven't changed that yet concerning the mode because I would like to have 2 security steps (TLS Key + Username Password).

        @viragomann
        Ok I removed the push route.

        Server:
        4abf5964-d4f1-410d-8c3b-199a8fdaa073-image.png

        So I use at the moment subnet.

        Client:

        e828729f-b1a6-4d95-bb35-7497f5c20733-image.png

        Maybe I have something else wrong in my configuration?

          @hispeed said in Remote Access / TLS + User Auth - Connection up but no LAN:

          Client:

          This looks rather like the client specific override page. However, it's the right place to do your settings.
          But you have something to correct:

          In IPv4 Tunnel Network you have to state the clients virtual IP. This must be part of the servers tunnel network, when using subnet topology, as mentioned.
          So since your server is 10.0.5.0/24, enter here "10.0.5.222/24".

          IPv4 Local / Remote Networks must be network addresses! Yours are IPs, but not networks.

          So into the IPv4 Local Network/s box enter "192.168.100.0/24",
          and into IPv4 Remote Network/s (clients side LAN) enter "192.168.20.0/24", if that's the proper network, you didn't mention.

              I set up your settings, tunnel is up but still i can't reacht the remote network.

              @Jarhead

              On both side I have this rule as the first rule.

              8c6e47f6-8091-45c8-9844-d9e4f4f95fb3-image.png

              I'm pretty sure this is because I don't see the IPv4 Routes entries in Diagnostic Routes belonging to the remote network from the client when I look on the server side.

                @hispeed Can you post the full vpn config from both sides?
                You have snippets of each and they're getting jumbled.

                Also, what does the openvpn logs show?
                Do you have the user/pass in the clients config?
                Do you have all the right cert's?

                Why are you opening ports on the client side?

                  Do you have all the right cert's?
                  As far as I know i'm pretty sure I have checked it and if they wouldn't be correct the connection is not working.

                  Why are you opening ports on the client side?
                  Which ports do you mean? I don't know I didn't open any ports as far as i know.

                      I hope this works since I'm doing a double post.
                      This is the follow up and client side configuration. The client side is also a Pfsense, so the connection will be from Pfsense to Pfsense.

                        @hispeed Get rid of the client specific override.

                        The tunnel networks have to be the same. Copy the subnet from the server to the client. 10.0.5.0/24

                          You're messing up the settings, again and again.

                          Configure the CSO as I suggested above, please. The tunnel network is wrong again.

                          In the client settings you must not state a tunnel IP. You can leave it blank or enter the tunnel network equal to the server settings.
                          And the Remote Network is wrong! This is your local network. In the Remote Networks box enter the server sides network!

                              I have checked it and corrected it. Yes you were right I messed it up.

                              I still get on the client this "Authenticate/Decrypt packet error: packet HMAC authentication failed" error. So i exported the CA and Client certifcate new.

                              Could it be because I used an ECDSA?

                              Keytype: ECDSA
                              secp521r1 [IPsec][OpenVPN]
                              Digest Algorithn: sha512

                              I also don't see on the server side no route to the 192.168.20.0/24 network into the tunnel: 10.0.5.0/24. So I think there is a problem. I also have to set the gateway manual on each interface on the server side because of my WAN configration which uses configuration override.

                                Custom options on the server Side:

                                9cf3f667-f7f8-442f-ba03-eb39871a9867-image.png

                                i added it but not on CSO config.

                                Now I can connect to the client side.

                                But why?

                                I see this has now ben created in Diagnostics / Routes:

                                  I'm still on older OpenVPN versions which have no support for this. So I don't know.

                                  Custom options on the server Side:

                                  i added it but not on CSO config.

                                  Yes, I think, that was the missing link, but didn't consider this.

                                  As far as I know, the route option is necessary to add the route in pfSense to OpenVPN. But also in the CSO you need to enter the clients network into "IPv4 Remote Networks", which is needed to set the route to the proper client within OpenVPN.

                                    @hispeed So I tried this in my lab last night and could not get it working although it should.
                                    To be honest, you're wasting your time. Just do a peer to peer with a /31 and be done with it.
                                    But if you want to keep trying....
                                    First, you do not need a CSO with only one client connecting. As I said, get rid of it. Not doing any good.
                                    Second, with remote access as the type, you're basically creating a "road warrior" vpn. Typically meant for one client to connect to one site. It doesn't enable other clients on the remote network access to the vpn. That's why I say just do the peer to peer as it's meant to be used. But you can configure a remote access for the entire remote LAN, see here:

                                    https://community.openvpn.net/openvpn/wiki/HOWTO#IncludingmultiplemachinesontheclientsidewhenusingaroutedVPNdevtun

                                    Again, I tried it, it's a waste of time when there's an option made explicitly for what you want.
                                    The biggest problem with remote access is the config doesn't give you the option to set "Remote IPv4 Networks" and peer to peer does.

                                    By the way, that error you're seeing has to do with the certificates. Did you create all certs on the server, then export the needed certs to the client, or did you create certs on server and create certs on client?
