          Hmmm no idea what this is. ;-)
          However please try to switch TLS Encryption and Authentication to TLS Authentication in your pfSense Client.

            @Rico Thanks a lot!! I was able to to connect after switching TLS Encryption and Authentication to TLS Authentication and than after that Added SHA1(160 bit)

            Now I am able to ping the AWS network from pfsense end but not able to ping the remote network (pfsense) side from the AWS end.

            I am not able to ping bidirectionally, Is this a normal behaviour in case of OpenVPN our some pfsense configuration needs to be done ?

              You need to setup your Rules in the Firewall -> Rules -> OpenVPN tab (pfSense WebGUI).
              For testing just do any-any and check if everything works.

                @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-----

                </tls-auth>

                  @johnpoz I have just downloaded the config from AS and followed this document.
                  https://www.netgate.com/docs/pfsense/vpn/openvpn/connecting-pfsense-to-an-openvpn-access-server.html

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

                    ☺

                    0_1549286645395_validateyourauth.png

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

                      My bad, missed it.
                      By the way do you know anything regarding Bidirectional ping part ?
                      I have added any to any config in firewall for all interfaces still it dosen't work.

                      Can you please help me in this on how to do it ?

                          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. 😑
                              But my guess is @johnpoz will come back with some ideas. 😀

                                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
