Question Can't get bridge network working.

Hi there!

I have a intel nuc which runs a server with several docker container and several services running on bare metal. I would like to run django project i'm building on a docker container in a VM using Virtual Machine Manager. I'm however unable to get the bridge network going, NAT works like a charm but I want to be able to access the VM from outside my network.

Here's my system info:
Code:
cat /etc/os-release
PRETTY_NAME="Ubuntu 22.04.3 LTS"
NAME="Ubuntu"
VERSION_ID="22.04"
VERSION="22.04.3 LTS (Jammy Jellyfish)"
VERSION_CODENAME=jammy
ID=ubuntu
ID_LIKE=debian
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
UBUNTU_CODENAME=jammy
Here's my ethernet info, my server is connected over ethernet and my wifi is disabled:
Code:
lspci -nnk | grep net -A2

Heres my network interfaces:
Code:
sudo nano /etc/network/interfaces
source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback
I've tried multiple guides to get a bridge working but all failed. I've tried to build a bridge network and add ethernet connection as a slave using nmtui but then I got the error that I can't activate the bridged network. I've also tried to add the bridge using brctl but that also did not have any effect. The weird thing is that when I've created a a bridge it was set on as DOWN and I've tried to change the status to UP, but when I do that the status in 'ip a' does not change, even after restarting the network service.

My server has an IP of 192.168.2.250 and my router had the IP of 192.168.2.254. However the ip range of my VM always ended up being in the range 192.168.122.*. The VM is running fedora 39 server and should have an ip of 192.168.2.251.

Does anyone have an idea what i'm doing wrong ?

Network interfaces file doesn't do anything on 22.04. You need to use Netplan. 2nd just because you set it up on the server doesn't mean you can get through your router. Have you forwarded the port from the router to the proper ip address? 3rd this may not be possible as the majority of ISP's block all incoming ports because they don't want people running servers on a home internet connection. You may need to upgrade to a business class plan to get unlocked ports.

Hi there, thanx for the reply, i will look into bridging with netplan!

I however do doubt your second and third point, but I don't know enough of it to know who is right. But currently all my docker services work great, also i can just buy a second physical server to host my docker container on there, does my router even spot the difference between a bare metal server and a VM? Isn't the whole idea that the server does not know if the server is virtual or physical? Could you please care to elaborate on that?

okay i've tried using netplan but getting some weird errors.
This is my netplan now:

Code:
network:
  version: 2
  renderer: networkd
  ethernets:
    eno1:
      addresses:
        - 192.168.2.250/24
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]
      routes:
        - to: default
          via: 192.168.2.254
  bridges:
    br0:
      interfaces:
        - eno1
      addresses:
        - 192.168.2.251/24
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]
      routes:
        - to: default
          via: 192.168.2.254
and this are my errors:

Code:
sudo netplan apply

I'm trying to get these to understand and trying to look for routing-policy in https://netplan.readthedocs.io/en/latest/netplan-yaml/ but i have troubles figuring it out. Can someone help me explain whats wrong?
