I'm running Proxmox VE 7.2-7.

sometimes when I was doing something,
sometimes backing up the VM, sometimes copying a lot of files in the VM,
sometimes when I finished playing the game in the VM(with video card passthrough) ......
The Proxmox VE host, and all of the VMs, and the local area network of my home...... Everything is crashed.
I can not connect to host and VMs, all other devices in my hourse can not connect to internet, and also cannot connect to the web admin page of the router.

After force restart Proxmox VE host, everything is OK again.

sorry my English is not good

Is your router virtualized on the PVE host?

No, Its a standalone router.
I'm very curious why Proxmox VE affects my router.

Have you checked the syslog around the time the PVE host stopped working?
Do you see something in the terminal on the display when the PVE host fails?

You may just run wireshark on a client to debug or try to set up a switch port mirroring and run wireshark on the mirrored port to see what's happening there.
