[Hetzner] Bridged config knocks out all network access.

[tompinn23]

Hello,

I can't figure out how to setup a bridged config on hetzner. I followed there tutorial and have an /etc/network/interfaces below

auto lo
iface lo inet loopback

auto enp35s0
iface enp35s0 inet static
    address 65.108.xxx.xxx
    netmask 255.255.255.255
    pointopoint 65.108.xxx.yyy
    gateway 65.108.xxx.yyy
    
auto vmbr0
iface vmbr0 inet static
    address 65.108.xxx.xxx
      hwaddress 00:50:56:00:28:BF
      netmask 255.255.255.255
      pointopoint 65.108.xxx.yyy
      gateway 65.108.xxx.yyy
      bridge_ports enp35s0
      bridge_stp off
      bridge_fd 1

When vmbr0 is disabled the internet works correctly however enabling it causes the ssh to fail and internet is no longer accessible from the host.

Are you using the same public IP for the enp35s0 and vmbr0? - if so, this shouldn't work.

Should I have the enp35s0 set to nothing then? I want a vm to have the additional IP to act as a router, whilst the host has the main IP.

Hi,

Should I have the enp35s0 set to nothing then?

Yes, e.g:

auto vmbr0
iface vmbr0 inet static
        address X.X.X.X/XX
        bridge-ports none
        bridge-stp off
        bridge-fd 0
