proxmox VMs are no network access after removed from cluster

[surfing713]

Hello all.

At the time around removing from the proxmox cluster, all VMs can't do networking at all, even ping the host and VMs.
I can start and connect VM from proxmox console, but no networking to outside of VM.
The proxmox server is configured bridge network and all static IPs (include VMs)
Any check point or suggestions to solve this situation ?
Thank you

Host network config (192.168.0.201) :


VM's network (192.168.0.209) and even can't ping the host :


Host also can't ping the VM, but it resolves VM's MAC address :

Hey,

can you check if ICMP requests from ping reach the host? You can have tcpdump icmp running on the host while running ping in a VM for that.

No packets are coming.
