OpenVPN stops everytime I connect



  • I have an OpenVPN server on pfSense with 1 WAN and 1 LAN port, no VLAN.

    What happens now is that everytime I connect to it and check out my service I notice the OpenVPN service has stopped due to an error and not being able to connect to the daemon. Weird thing is that the Windows desktop client does not drop the connection due to the server being unreachable. But on the other hand I can't access the pfSense admininterface either when connected.

    Does anyone have an idea what is going on?



  • I have found the problem! When I use hmac OpenVPN stops/crashes. When I do not use it everything runs smooth. Also tried using hmac without hardware encryption but didn't work also. I'm a bit disappointed that OpenVPN crashes when using hmac :( Does anyone have an idea on how to solve this?
