The lease comes with a renew interval of aprox. 24 hours, a rebind interval of about 6 days, and an expiration interval of 7 days.
It’s normal for a DHCP client to attempt renew when the renew timer (T1) expires, so pfSense is just doing what it’s suppose to.
But as soon as a renew reqeust has been sent, the line stops routing traffic, so Orange must consider something wrong with that attempt, and shut down routing.
I then have to do a full DHCP release and renew to get another ~24 hours.
It’s a single stack IPv4 only setup.
