      Ok so no connection logs from a phone app, you're going to need to connect from a PC to get that I think.

      However the fact it connects and doesn't pass traffic to some servers seems exactly like what you're seeing in pfSense. It could just be your ISP blocking the traffic.

              to be clear.

              its not working using their equipment + pfsense and openvpn

              but its working over wireless using the same equipment using the app + openvpn?

                That looks like a Windows application. Are there logs there showing how it is connecting?

                You might try using their TCP setting instead, if you know what those are.

                IPSec is far more likely to be blocked, on the standard ports at least.

                        So OpenVPN does not work from Windows using either UDP or TCP?

                              It shows TCP on the phone app.

                              If you see no traffic when connecting from Windows then there's no point trying to get pfSense to connect IMO. Something is blocking that traffic.

                                    Should I undetsrand that a OpenVPN client, build into a ddwrt, connects fine to your VPN, and pfSense doesn't ?
                                    From the same place ?
                                    You are alternating the routers ? (first you put pfSense in place, test = doesn't work - and then the ddwrt and that one works.)
                                    The fact that OpenVPN works fine over your connection using the ddwrt mean : it isn't your ISP that blocking you. I presume same ports, protocol etc.

                                    There is hope : it's a pure "settings" issue.
                                    I can connect just fine to ExpressVPN using the OPenVPN client :

                                    I used to setup and debug the client - keep n mind, thius explantion isn't 100 % correct - I made some changes (don't remember which ) - it's all a "read the logs, look up the messages that look like an error, Google them up, and do what other prospose)

                                    The 3 "Options error" are meaningless for pfSense.

                                    Also : Your issue isn't probably VPN related. Other changes in the general pfSense setup can influence the connection, for example : bad MMS or MTU, etc.

                                    Btw : It connects. I didn't pass any traffic throughit, because then I have to change my firewall rules, setup other gateways, etc.

                                    So,

                                    i feel there is a small issue ...

                                    No issue I guess.
                                    Just make it work.

                                    edit : these are my custom options :

                                    persist-key
persist-tun
tls-client
verify-x509-name Server name-prefix
remote-cert-tls server
key-direction 1
route-delay 2
tun-mtu 1500
fragment 1300
mssfix 1450
auth-nocache

                                    Some of these are probably not needed.

                                    No "help me" PM's please. Use the forum, the community will thank you.
                                    Edit : and where are the logs ??
