          Ok, progress !
          Connections attempts are coming in now.

          Question : one of these is the IP you were using with your client OpenVPN device :

          f3e47169-6af2-45a2-839d-c92e3b39bb70-image.png

          ?

              You are aware that every Internet device can access any IP ?
              You can go wherever you want, so can everybody else.
              What you are seeing are 'random' IP addresses that 'try' to connect to you WAN IP, protocol UDP, port 1194. They 'test' your OpenVPN.
              This looks scary if you've never seen this before, but don't worry, OpenVPN was created to handle this situation. You are probably using certificates as an access control mechanism :

              e840124b-2b44-42dd-b4c1-ffa080ce3c8b-image.png

              you can see these certificates - you saw them in the ovpn file you've exported to your client - and it's impossible to guess these.

              You Office PC is a PC that uses the Internet to go to you OpenVPN? right ?
              This Office PC should not be part of your pfSense LAN network.

              Normally, to test, you install this app on your phone (an iOS also exist) and you use your phone with the Wifi de activated. Use the data of your phone provider to connect to your ISP WAN IP.
              You know it works, as connections are already reaching your OpenVPN server ^^

                Ya I thought that "may" be some attack attempts. BUT:-
                I am in UAE now and my home is in India where pfsense is located.
                My home IP is 59.88.4.40
                but openvpn client from my office pc is trying to connect to 117.196.173.241:1194.

                I am using dyndns at my pfsense end. As per my research this ip 117.196.173.241 doesnt belong to my dyndns.

                This makes me kind of total confusions.

                I tried both User auth as well as TLS modes.

                Attached the latest openvpn log from pfsense. Plz chk if u can see anything interesting ?

                  That makes no sense.
                  If you know your that the IP you need to contact is is 59.88.4.xx then why would you (have it) use 117.196.a.b ?
                  DynDNS issues ? Who cares. Handle that one later.
                  For now, set up the IP like :

                  85effcbf-0c0c-4d1a-b1d7-df75613ed0d9-image.png

                  export the Client OpenVPN config.
                  Import the config in the client.

                          I set the Device Mode in server configuration as "tun" only no "tap" . So I shudnt get TAP adaptor in my connected clients rt ?

                          Is that matters for not getting GW and DNS in client ?

                            When you set up a OpenVPN server using TUN, you have to create a corresponding (redo) your OpenVPN client side accordingly.
                            Actually, every time you change something on the server side, you have to redo your client config also.

                            Normally, you export the openvon config on pfSense to an opvn file, and you import this file on your OpenVPN client.

                                Your client side ( ? ) as showing a tap connection.

                                    Did you even provide a DNS server in the OpenVPN server settings?

                                    A Default Gateway is not meant to be set on the VPN interface, as far as I know. There is no need for it.

                                    What's your actual issue now?

                                      I assigned dns in server settings and client getting the same.
                                      But issue is client is not getting internet.
                                      I even added redirect-gateway def1 option also.

                                      My conf file is as below:-

                                        You should not post your client certificate and TLS key in a public forum.

                                        And the server config would be more interesting than the client.

                                        In the server settings you have "Redirect gateway" checked, I guess?
                                        And again the question: Did you even state a DNS server?

                                          my mistake on certificate
                                          As I stated, I have stated dns in server settings and I am getting tunnel IP, subnet, DNS IPs and no GW in my TAP adaptor in client PC. and consequently NO internet. I can access home network.

                                            How do you want to access the internet?
                                            Do you want to pass internet traffic over the VPN, so that yor get the home WAN IP or do you want to access the home LAN and go to the internet using your local WAN (split tunneling)?

                                            Please post the server configuration and the clients log.
