[Solved] Losing WAN Access

[s4rs]

Sometime after I updated to OPNsense 23.1.5-amd64 the system loses access to the WAN. I have OPNSense running under Proxmox. In the Proxmox server I have a quad port Intel I350 GigE adapter. One port is passed through to Opensense. I have the interface vlan'd, one for the wan, one for home lan, and one for home guest. I still have a parent set up for the wan. This setup has been rock steady for many years.

My question is how to best troubleshoot this issue. Proxmox logs show nothing. What logs in Opnsense should I look at?

I have a back up system, SMC Atom C2758 running Proxmox with Opnsense, and it is rock solid (using it now to post this). This system is setup with a vm vlan aware bridge interface. It does not use a parent for the WAN, just three vlans setup on the bridged network.

Let me know anything else I need to post to help troubleshoot this.

Turned out there was an issue with the switch my Opnsense setup is connected to. I replaced the switch and the drop issues went away. Can't say what the switch issue was. I always had strange issues with devices on that switch.
