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.

Hi Chris,
i am getting the same error as above and here is my configuration
on host:
Code:
auto lo
iface lo inet loopback

iface ens192 inet manual

iface ens161 inet manual

iface ens224 inet manual

iface ens256 inet manual

auto vmbr0
iface vmbr0 inet static
        address 10.200.10.5/24
        gateway 10.200.10.254
        bridge-ports ens192
        bridge-stp off
        bridge-fd 0

auto vmbr1
iface vmbr1 inet static
        address 10.10.10.11/24
        bridge-ports ens161
        bridge-stp off
        bridge-fd 0
#vm

auto vmbr2
iface vmbr2 inet static
        address 20.20.20.21/24
        bridge-ports ens256
        bridge-stp off
        bridge-fd 0
#sync

please don't necrobump old threads - create a new one with your issue so it's easier to keep track.

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
