Hello,

I need to separate completely the routing and traffic of WAN and LAN

I have vm1 on proxmox1
I have vm2 on proxmox2

each proxmox has a two nics one for WAN and one for LAN
the two proxmoxes are connected to each other on the LAN interface via a switch

The two vm's have two nics vmbr0 connected to WAN and vmbr1 connected to LAN

each of the vm's can ping both proxmoxes LAN address

I cannot ping the other vm from none of each vm

what am I missing ?

for vm1 and vm2, are the LAN interfaces on the same subnet/vlan? A diagram
with sample subnets might help, my initial suspect would be a ip route
issue if they're not on the same vlan.

If both VMs have their vnic attached to vmbr1, then it might be also worth
having a look at the firewall on the o/s inside the VM. If that's enabled
on both sides, it could potentially block ping requests...
