VM have to reconnect manually after pve restart networking.service

Hi there!
VMs can't ping route after pve restart networking.service and won't able to reconnect automaticlly. I have to toggle firewall flag of network device net0( enable firewall if it is disable, vice versa) to resume VM's network. Impacted VMs' system are debian12 and win10.
Neither disabling firewall of Datacenter, Node and VM, nor disconnecting then connecting this network device net0 would work.
Any idea?
