Are those network settings correct? What am I missing?

[Nikole]

Hello people,

I have been trying to figure out why the following network setup does not work on my new server (Hetzner).
Can you see where am I making a mistake?
If have tried several other settings but no luck.
KVMs with public IPs connected via vmbr0 are working OK.
KVMs with internal IPs (192.168.0.xxx) connected via vmbr1 cannot reach the Internet.
Any help is welcome!

Thanks
Nikole
