I updated OPNSense to 24.7.11_2 last week and ever since WAN is dropping out about the same time every day, it will reconnect but it will end up on a cycle of drop and reconnect until I reboot the firewall.
Looking at the logs I think that OPNsense is trying to force a renewal of the WAN address:
2024-12-21T20:56:55 Notice opnsense /usr/local/etc/rc.newwanip: IP renewal starting (new: X.X.X.109, old: X.X.X.109, interface: wan, device: pppoe0, force: yes)
2024-12-21T20:56:55 Notice dhcp6c RTSOLD script - Sending SIGHUP to dhcp6c
2024-12-21T20:56:55 Notice dhcp6c RTSOLD script - Sending SIGHUP to dhcp6c
2024-12-21T20:55:57 Notice opnsense /usr/local/etc/rc.newwanip: Failed to detect IP for interface wan
I'm connected to my ISP over PPoE so should not be trying to do a forced renew.
Any ideas?
