Hi,
I'm currently testing SDN with 7.4. I configure a VLAN zone as per https://pve.proxmox.com/pve-docs-7/chapter-pvesdn.html and https://pve.proxmox.com/wiki/Software-Defined_Network#pvesdn_setup_examples.
This is a very basic setup with a Zone "cluster1" (no DNS, no DHCP for now) and a VNet "clus1vn" with tag 10.
Two nodes are in the zone: pvelab4 and pvelab5.
There is one VM per node. The VM cannot ping each other. This might be a very stupid misconfiguration but I'm struggling to find the root cause, thus any help would be greatly appreciated.
When I migrate one of the VM to the same node than the other, the ping works.
(same conf on pvelab4).
Then I reconfigured 2 test VMs to use the new VNet instead of vmbr0.
The network configuration of each pve node is:
