How stable is OpenVPN?
-
When you try to connect with an external client do you see states created on the WANfor the incoming connection attempts?
I'm not aware of any issue in OpenVPN itself that behaves like that.

@stephenw10: I am not familiar with what states are and what that list would signify.
Do you mean entries like these:
I don’t believe that there were any entries in the states table showing evidence of my failed attempts to connect to the OpenVPN server, before I restarted the service. However, I will need to verify this, when I encounter it being down the next time.

Nope, those are states on the OpenVPN interface, so inside the tunnel. What I would expect to see are states on the WAN on whatever port you're running OpenVPN on, UDP 1194 by default.
If you don't see those states then the VPN traffic from the clients is not arriving which would explain why there are no logs for connection attempts. -
@stephenw10: … And if a restart of the OpenVPN server fixes things, then that’s a sign that there was nothing else wrong upstream from the gateway, I would think.

Except that we've seen in the other thread that doing so is triggering, at least, dpinger to restart. So it could be doing more than you think.
