OpenVPN service crashing
-
I have a central setup of dual XG-7100 setup as a high availability cluster. Meaning only one is active at any given time.
I have 5 external locations where each of them have a SG-3100. On all external locations we have en fiber WAN connection and each SG-3100 has an internal LTE card.
Our setup is as follows. Each SG-3100 establishes 2 OpenVPN tunnels to the XG-7100. One over the Fiber, which is the primary and one secondary over the LTE connection. To ensure proper routing with failover and failback, we use FFR BGP routing.
Now under normal circumstances everything works perfectly. If we pull the fiber, traffic fails over to the LTE, and once the fiber is back up and the VPN is established, traffic fails back to the fiber.
That is until the OpenVPN services fail. We are unable to restart the services, only option that works is to reboot the SG-3100. Once rebooted everything resumes operation.
Funny thing is that this has up to now ONLY happened on one of the SG-3100, which we replaced, but it continued. We have had a theory that it must have been something related to the network on the external site. We never found a couse though. Problem has now gotten worse as we now have the problem on 2 external sites. The new problem site have had to be rebooted every day or two...All boxes run 2.4.5 except one where we test the newest PFsense+ versions, it is though not one of the problem sites.
There is no indications of the failures in the OpenVPN logs.Can anyone help, this is frustrating as hell??

Anyone?
This is still an issue, we are getting desperate!The only solution right now seems to be a scheduled restart every night.
But to me that is like peeing your pants to stay warm, not solving the problem.So are there really no one out there, that has any idea, how to solve this issue?
