I'm seeing odd behavioral where the LAN Interface (and sometimes the WAN interface) shows "link state changed to down" then "link state changed to up" on OPNsense 22.7.10_2-amd64. I at least as far as I can tell never loose internet access. All seems to be functioning. My LAN interface is a static IP, the WAN is DHCP. Any ideas. Also they don't get any more newbie than I on OPNsense. This up/down sequence happens multiple times a day.
Happens to me too with OPNsense 23.1.1_2... The problem is I run nextdns in the router, and when this link state thing happens, nextdns is unable to resolve for a few minutes and I either need to wait with no DNS or restart nextdns when that happens.
