Oh, ok, I understand. So proxmox is not routing packets. 
For me, this is not "routed" mode.

what you do is something like bridging, but spoof guest mac address with host mac address.



If a routed setup, the provider give you a subnet range, routed to the proxmox main ip.
and guests use proxmox ips as gateway.


So maybe are we talking about 2 differents this ?


(I need to check the forum, I had helped one use some time ago with routed network on hetzner, with differents sub-ranges)

The VMs are in the same network as the host in above use case, so we use the same setup. 
The provider will tell you what gateway you need.

But this is nothing we can solve anyways.
