      @shahid3507 said in Issue Connecting pfsense as a client to OpenVPN Access Server:

      tls-crypt /var/etc/openvpn/client1.tls-crypt

      I am like 99% sure that openvpn-as does not support tls-crypt.. Atleast not current 2.6.1 version..

      The AS stores its config in a db, so its a bit harder to show - but there is zero place to turn on crypt for tls in the gui. And do believe reading something about it - they did a while back enable crypt for the connect client (ios and android) but I do not believe the AS server supports it as of yet.

      When you setup the client in pfsense - did you download the client config from the AS to validate what you need to set?

      example - just download my client config from my AS

       Automatically generated OpenVPN client config file
      # Generated on Mon Feb  4 07:15:51 2019 by ns1
      # Note: this config file contains inline private keys
      #       and therefore should be kept confidential!
      # Note: this configuration is user-locked to the username below
      

      Certs will all be inline

      And its just doing auth

      key-direction 1
      <tls-auth>
      #
      # 2048 bit OpenVPN static key (Server Agent)
      #
      -----BEGIN OpenVPN Static key V1-----

      -----END OpenVPN Static key V1-----
      </tls-auth>

        @johnpoz I have just downloaded the config from AS and followed this document.

          Seems you didn't follow the part where it says
          " pfSense may be configured to use the info in the .ovpn file"

          โ˜บ

          And not encryption and auth. Double check all your other settings.

          example here is my client config form pfsense for my openvpn-as server

          dev ovpnc3
          verb 1
          dev-type tun
          dev-node /dev/tun3

          #group nobody

          daemon
          keepalive 10 60
          ping-timer-rem
          persist-tun
          persist-key
          proto udp4

          auth SHA256

          down /usr/local/sbin/ovpn-linkdown
          local 64.53.<snipped>
          engine rdrand

          client
          lport 0
          management /var/etc/openvpn/client3.sock unix
          remote <snipped> 1195

                The tunnel is connecting and I am able to ping the AWS side (Access server subnet) but when I am trying to ping the client side form the access server or the subnet than it's not reachable.

                    Not atm, I don't have any experience with OpenVPN AS or AWS, sorry. ๐Ÿ˜‘
                    But my guess is @johnpoz will come back with some ideas. ๐Ÿ˜€

                      Ping what exactly? Can you ping the lan IP of pfsense from your aws side?

                            There was a need to add route for specific traffic and change the OpenVPN settings to act as site to site VPN.
                            It is now working.

                            Thanks for your help @johnpoz @Rico
