Reboot required after outage

[ARCHmatux]

Hi All,

I've got an ongoing issue that I've had both with OPNsense and previously it's main rival before I switched.

Essentially the problem is that if the cable modem loses connectivity to the internet for a period of time, when it regains connectivity, the WAN IP on OPNsense is not renewed unless I reboot.

The cable modem does not shut down it's "LAN" site port when it loses connectivity so OPNsense will not see a link state change when the cable modem loses connectivity or comes back. Additionally I now run OPNsense virtually so it will certainly not see a link state change even when the cable modem is rebooted.

Would it be possible to configure OPNsense to attempt to renew the WAN IP via DHCP every minute while the WAN gateway monitor is offline?

If not, would https://forum.opnsense.org/index.php?topic=10924.0 still be applicable?
