      Hey!

      I have a problem with my OpenVPN client on my pfSense 2.4.1-RELEASE firewall, running on an Up Squared. The client (seemingly successful) connects to some ExpressVPN server, but disconnects every few seconds ending in huge packet losses etc.

      It is not a problem of my internet connection - when I use the config of ExpressVPN on a computer in the network (with disabled VPN client on my pfSense firewall), there are no disconnects.

      What else do you need?

        I'm having the exact same problem. ExpressVPN directed me to the pfSense forum.. so they have no idea. They said their setup guide was written by one of their customers.

            That does not mean openvpn disconnected. That means that the GUI status page or widget probed the openvpn service and then disconnected from the management interface. Your logs are probably too verbose to see what's actually happening. Turn down the logging to verb 3 or 4, and ignore any line with MANAGEMENT in it.

            I know your config claims it's only using verb 3 but that looks like a lot higher log detail than 3.

              I had similar issues from 2.3 versions, I also had disconnects from my computer. not with expressvpn but with another provider.

              The disconnects disappeared when I disabled gateway monitoring both at my default gateway and the VPN gateway.

              Login to your pfSense and visit System/Routing/Gateways. Click the edit button at your default gateway and at your VPN gateway and put a tick on "Disable Gateway Monitoring" and "Disable Gateway Monitoring Action" . Save your settings and reboot your router in order to make sure that they are applied.

                Wow! That's it! Previously I had huge packet loss rates (50% and more), nor everything seems to be fine (means not a single packet lost after 100 pings :))) Thank you!!
                I will send ExpressVPN a link to this thread so they know it's not really their fault :)
