      I have followed a tutorial for configuration and tried a number of changes to no avail. I can't tell for sure if connection is actually being made or not, but I am able to use a Ubuntu client to connect to the same server, so this appears to be some issue with pfSense setup.

      The configuration is:

      dev ovpnc4
verb 5
dev-type tun
dev-node /dev/tun4
writepid /var/run/openvpn_client4.pid
#user nobody
#group nobody
script-security 3

ping-timer-rem
persist-tun
persist-key

comp-lzo adaptive

tls-client

remote-random

tun-mtu 1500

tun-mtu-extra 32

mssfix 1450

persist-key

persist-tun

reneg-sec 0

remote-cert-tls server

      Note that COMP-LZO setting is one my tweaks; the recommend setting did no work either.

      I have a suspicion that the issue is with my Motorola Cable Modem (MB7420), which is in bridge mode, but before I run out and get another I thought I might push on this a little harder. Maybe there is some issue with the suggested configuration?

      Any ideas welcome.

      Cheers!

        @wpmccormick said in OpenVPN client not connecting: Connection reset, restarting:

        Why are you using TCP? It's slow compared to UDP. Your document said to use SHA512 for your Auth digest algorithm. Put the compression back to No LZO Compression [Legacy style,comp-lzo no].

          I would double check that you properly extracted all of the keys, certs, CAs, and TLS keys and that they are all set properly.

          It looks like they are resetting the connection immediately after the connection is established. No reason given on this side. You might try bumping the log level up a notch to see if you get anything else.

            I tried the same server with UDP from the Ubuntu client and verified that it can work there; it faster as well (according to speedtest.net).

            However, no luck from pfSense. What are the firewall rule requirements, beyond allowing the client out on the LAN side? I don't believe there should be any WAN side rules.

              None unless you have filtered outbound connections. In that case the address, protocol, port of the server.

              Nothing special about pfSense here. Put all the right things in the right places and it will work.

                Let me review how I extracted all of the keys, certs, CAs, and TLS keys:

                ... and went to System->Certificate Manager->CAs->Add; Method = Import an Existing CA; and pasted everything between <ca> and </ca>, including the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----. I pasted everything between <tls-auth> and </tls-auth> to VPN->OpenVPN->Clients->Edit->TLS Key. The only other key-certy thing is the VPN->OpenVPN->Clients->Edit->Client Certificate, which is set to webConfiguratorDefault - and I don't recall where that came from - but it is what it is.

                I had some outbound filters so that my ubuntu VM can't get except through his VPN, so I disabled those just to test. I restarted the pfSense OpenVPN client service and captured the startup and connection log output, if that helps.

                One of the lines that seems suspect is TLS Warning: no data channel send key available.

                  If this problem is due to some issue with my modem, how would I go about proving that?

                    Motorola Cable Modem (MB7420

                    Awesome modem! I used one with multiple OpenVPN instances for a couple years before I upgraded to an MB8600. That modem only does bridge mode. I very seriously doubt that is your issue.

                      Could it be some issue/conflict with pfBlockerNG add blocker?

                        I disabled the ad blocker and associated fw rules ... no change.

                        One thing I can't understand is that the outbound LAN rule where the VPN gateway is specified is passing all traffic, even though the gateway/VPN is not connected.

                            I was just coming to tell you to go very closely over your settings and look for the smallest error.

                            Nice job!

                              I had a case once where nothing worked until you changed the compression on both sides from No compression to Adaptive LZO. That makes no sense to me whatsoever, but it worked one way but not the other.
