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?

Did you happen to create a ZFS/Proxmox snapshot before upgrading to 26.7.3? If you need internet up immediately, rolling back to your 26.1 snapshot will confirm if it's strictly a 26.7 regression.

If you stay on 26.7.3, revert the net.route.algo.inet.algo tunable back to default first so it doesn't mask the underlying gateway issue. Then check clog /var/log/system.log | grep routing from the shell to see the exact sequence when vtnet1 obtains its ip

So unfortunately I recently upgraded proxmox to latest version. Unknow to me it deleted the snapshots I had and I was relying on them being there. Ugh stupid on my part.

I removed the routing tunable setting and rebooted. Searching the log I see vtnet1 getting the ip address and gateway. It successfully sets them. However no access to internet. Additionally the dhcp script is running every hour to renew the address. That seems excessive.

I am getting the feeling I will need to rebuild this system, but am hesitant to use 26.7.3.
