hello all

i am stuck and i cant seem find the solution

we have 2 Proxmox

1. proxmox on a single server with opnsense. this server services multiple public ips (which will be managed with opn)
2. a proxmox cluster with 4 Proxmox hosts
both are connected over a 1 gb switch (ceph and vmotion has an own 10gb connection)

the first proxmox seems to be configured correct. a test vm gets an IP over the vLAN from opn - everything works

the issue is: how i get the traffic now to the other proxmox cluster ?
how the proxmox acceppts traffic from vlan x
the all 5 proxmox server can ping each other over the normal nic1 (which would be the 10.10.12.10-13 and 254)
the subnet 172.16.61.0, with 16 times 28 ranges, vLAN 111 to 126

what and where do i need to configure to accept vLANs on proxmox level ?

any hints ?

PS: everything in one proxmox and opn, serving vms - works
just the way to the other site doesnt work
