Description

Hi

I recently noticed that after upgrading pfSense from version 24.11 to the newer 25.07.1, the firewall log started showing blocked messages: "lo0 Default deny rule IPv4 (1000000104)".
I have a LAN 192.168.0.0/24 and an OpenVPN site-to-site network 192.168.255.0/24. This worked in version 24.11 and I have not made any changes, but now I am unable to ping the destination network, and the remote side cannot access the local network either.

Has something happened in the update that could explain why this no longer works?
