Hey!
I use Hetzner and have a vSwitch there, which was connected to the so-called "Cloud Networks" by me.
The steps for this were taken from here:
https://docs.hetzner.com/cloud/networks/connect-dedi-vswitch/
I did not use the network config 1:1, but adapted it to my setup.
The problem:
I cannot reach any IP of the cloud network from created VMs.
From the Proxmox host itself, however, without any problems.
I can also reach the private IP of the KVM from the Cloud Network, but not from the KVM to the Cloud Network.
Apparently, the routing I do on the host is ignored.
I always have to define the routing again on the VM itself using:
Is there a way to fix / do this directly on the host?
I don't want anyone can see or change the routing there.
About the VM setup:
Public and private IPs run over two different NICs at the VM.
My network config from the host:
