loss of connectivity after running for a few days

[Tupsi]

Since upgrading to the 2.7.x track I suffer from a loss of connectivity whenever my opnsense is running for a few days. The issues always presents itself in the same way that part of the internet is no longer reachable, even though dns resolution still works. The problem is "fixable" with a simple reboot of opnsense.

Can someone point me to a place of logs where I might find the source of the problem? Currently I feel a bit helpless to pinpoint what the problem is.

My opnsense is configured to use both v4/v6 dynamic IP from the provider. That worked flawless so far until I switched to the 2.7.x track. I am using the unbound dns server instead of dnsmasq. Tried disabling the blocking sites feature there, because it felt like a bit of a misguided blocking of unbound, but the problem returned nonetheless.

Any help pinpointing that down what be much appreciated. Until then, no biggie and I restart the router whenever my wife shouts "Internet geht nett!!!" ;-)

Hope you all had a great christmas and wish you a great start in 2026!
