Problems with upgrade from 26.1 to 26.7.3

[Vulhunter25]

So I upgrade from 26.1 latest to 26.7.3 today. All seemed to go well but after final reboot, internet connection is not working. Provider is xfinity/ Comcast. The wan interface seems to dhcp but the system log has the following messages:

Interfaces.php: ROUTING: refusing to set interface route on addresses wan(vtnet1)

Error opnsense/interfaces.php ROUTING: not a valid wan interface gateway address: 'missing'

In interfaces:overview the wan shows an ipv4 address and a gateway address.


I did see notes about routing issues and set the tunable net.route.algo.inet.algo to radix4 this had no effect on issue.

This is a virtualized firewall in proxmox that has worked fine for 5 years.


Advice on where to go from here?
