To set up a bridge network on Ubuntu, follow these steps:

1. Install the bridge-utils package by running the following command in the terminal:

1

sudo apt-get install bridge-utils

1. Disable Network Manager by opening the file /etc/network/interfaces in a text editor and commenting out any lines that start with "auto" or "iface". Then restart the networking service by running the following command:

1

sudo service networking restart

1. Edit the file /etc/network/interfaces and add the following lines:

1
2
3

auto br0
iface br0 inet dhcp
    bridge_ports eth0

Here, "eth0" is the name of the interface that you want to bridge. Replace it with the name of your actual interface.

1. Restart the networking service again:

1

sudo service networking restart

1. Verify that the bridge network is working by running the following command:

1

brctl show

You should see a bridge named "br0" with the interface "eth0" added to it.

That's it! Your Ubuntu machine is now connected to a bridge network.
