Description Kurt Jaeger freebsd_committer freebsd_triage 2022-07-31 11:28:55 UTC 
I had several cases where an upgrade from 13.0 -> 13.1 with an
active ipfw ruleset:

# firewall, ipfw based
firewall_enable="YES"
firewall_type="OPEN"

caused the host after reboot to loose ipv4 connectivity.

It probably works if one sets firewall_enable to NO before the reboot
with the 13.1 kernel, and enables it after the final fbsd-update install
and does another reboot.
