Setting vmbr0 makes me lose ssh access and makes my VPNs stop working.

[Moofies]

My current /etc/network/interfaces file is:
auto lo
iface lo inet loopback

auto enp5s0
iface enp5s0 inet static
address 192.168.86.204
netmask 255.255.255.0
gateway 192.168.86.1

auto wlp4s0
iface wlp4s0 inet manual
source /etc/network/interfaces.d/*

but I want to setup a container for a minecraft server, so I decided to set up vmbr0.

To do this I changed my /etc/network/interfaces file to:

auto lo
iface lo inet loopback

auto enp5s0
iface enp5s0 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.86.204
netmask 255.255.255.0
gateway 192.168.86.1
bridge_ports enp5s0
bridge_stp off
bridge_fd 0
bridge_maxwait 0


but after doing this and sudo systemctl restart networking, I lose ssh access and my openVPN connection to my server stops working.

Is there something I am doing wrong?

Hi,

Did you try same your config but without `bridge_maxwait`? i.e.:

auto lo
iface lo inet loopback

auto enp5s0
iface enp5s0 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.86.204/20
gateway 192.168.86.1
bridge-ports enp5s0
bridge-stp off
bridge-fd 0

try adding the MAC of your enp5s0 to the bridge, like
auto vmbr0
iface vmbr0 inet static
address 192.168.86.204/20
gateway 192.168.86.1
bridge-ports enp5s0
bridge-stp off
bridge-fd 0
hwaddress 0c:c4:7a:2a:44:bf <--- your MAC

Thanks for your help guys, I'm still not really sure what was wrong, i just completely reinstalled the whole thing and then used the config from earlier. It worked though, TYSM!
