Unable to connect VM to internet with one additional IP (Hetzner dedic)

[rootroot]

Hi,

I am unable to connect my VM to network. I've been following hetzners guides on bridge, but still no ping.

This is the guide I have been following. I have also tested the routed option, but still no go.

What am I doing wrong?

Host's enp0s31f6 is bridged to vmbr0 and has the same IP address. This will not work (a bridged NIC should never have an IP address). AFAIU in case of "routed solution" you must not bridge the physical NIC; however for provider specific issue contact their forum.

In general it helps to follow IP packets (when e.g. runing a ping) via tcpdump.
