Perform a ping from VM to another node in the cluster

[proxmox_larry]

Hey guys,

in my environment it is possible to perform a ping between the nodes in the cluster.
Nevertheless I can not ping a node in the cluster from my VMs.

Do you know how to solve this issue.

Thanks!

Hi,
please post your network configuration cat /etc/network/interfaces and the container config pct config <CTID> in order for us to help you.

Hey, I first have to set a network device from my VM to the Host, which has an IP adress in the Host segment... I think that's the problem

Presumably, your VM's are on different bridges than your proxmox management interface is.

Many people would consider that a good thing. Your VM's shouldn't necessarily be able to ping your cluster nodes unless they have also been assigned an interface on the same bridge intentionally.

Many VM's should not be on the management network. Some should. Depends on their purpose.

I use the ip range 10.10.10.x/24 that I created myself so there is no Gateway, I just want my vm to be able to ping other vms and other nodes in this range
