Pinging vm on node1 -> vm on node2

[barhoumania]

Hello friends;

i have bought two bare metals from OVH and on each bare metal i have installed proxmox ;
after that i created a Data Center with the two nodes ;

Each node has its own public ip + i have created some vlans and private network so i can assign ips to VMs to access to net. everything is working so well.

PROBLEM: My problem now is that i want the vms on node 1 ping vm on node 2 and vise versa ;
i dont have any switch nor hub. how can i fix the problem?

Please can any one help me ?
Thanks in advance

Please note that ping is not the best way to test IP reachability because based on the default settings of different OS / firewall / ... the target VM can be reachable but maybe filter out incoming ping requests.

If these VM's are Linux with SSH server on them a better test could be trying to SSH from one to the other and the other way around.

More info about the network structure would also help narrowing the problem :
- config of vmbr's ? VLAN aware ? linked to what interface of the server ?
- what are the tagged / untagged VLAN's on the PVE side ?
- same question on the switch side ?
- what purpose for each VLAN + IP range and gateway ?

The content of /etc/network/interfaces + VLAN plan would be a good starting point IMHO.

Have a nice day,
