Can,t ping vm from pc

[cd0101]

I reinstalled proxmox and created a debian vm. I have the standard vbr 0 Bridge. I can ping the VM from the pv's PVE host and I can ping Google from in the VM the VM gets an IP address but if I try the Ping the VM for my PC I can't reach it

what am I missing? The weird thing is if I make a CT instead of a VM I have no trouble pinging.

Hi,
if you can ping a container attached to the vmbr0 then this indicates that the network layer should be fine. Please check that your PC is in the same subnet as your VM and that there is no firewall interfering with the traffic.

In both cases pc in diiferent subnet. Only diff is if i create as ct, no issue. If i create as deb 12 standard vm, cannot reach vm

So you rely on the Proxmox VE forwarding the packets from one subnet to the other one? Or do you have dedicated routes. You could inspect the traffic on the vmbr0 via e.g. tcpdump by tcpdump -i vmbr0 icmp to see if the packets reach the bridge and what their source and destination IPs addresses are. Further, you might want to inspect the output of ip neigh and ip route on the Proxmox VE host.

All of proxmox in same physical subnet given by my phusicql router. My pc is in other subnet. Will try those commands.
