      My box is Pfsense Version 2.6.0-RELEASE (amd64)
      built on Mon Jan 31 19:57:53 UTC 2022
      FreeBSD 12.3-STABLE

      Today, after 170 days online, we added a second Ethernet card, prompting us to temporarily shut down the system. Approximately one hour later, we received reports that certain destinations were unreachable. To cut a long story short, one of the tunnels added the following route to the route table:

      192.0.0.0/2 192.160.51.2 UGS 11 1500 ovpns3

      This addition practically made it impossible to access numerous sites on the internet. This tunnel lacks any special configuration; it only includes the essential settings for basic functionality with no custom options.

      Could there be a configuration that I am overlooking that would result in the addition of this route? It's important to note that I have not manually added this rule or route. Disabling the OpenVPN server causes the route to disappear.

      For testing purposes, I'll keep the tunnel disabled.

      Any insights or ideas?
