In a virtualized environment, you may have multiple virtual machines and network interfaces on the host machine. Using a bridge allows them to communicate on the same network. This facilitates direct communication between virtual machines and enables easy interaction with the physical network.
Choose one of the following options:
Command Line Configuration#
1.Create a bridge device
nmcli c add type bridge autoconnect yes con-name br0 ifname br0
2.Configure bridge IPv4
Dynamic allocation
nmcli c modify br0 ipv4.method auto
Static allocation
nmcli c modify br0 ipv4.method manual ipv4.address 192.168.3.10
nmcli c modify br0 ipv4.gateway 192.168.3.1
nmcli c modify br0 ipv4.dns 192.168.3.1
3.Delete the existing wired connection
nmcli c delete eno1
4.Bind the network card
nmcli c add type bridge-slave autoconnect yes con-name enp3s0f3u2c2 master br0
5.Restart Linux
GUI Configuration#
Wireless network card needs to be set to 4addr mode
# /etc/udev/rules.d/91-wifi-4addr-mode.rules
ACTION=="add", SUBSYSTEM=="net", ATTRS{address}=="04:cf:4b:21:76:0e", RUN+="/usr/bin/iw dev $name set 4addr on"
# Replace address with the MAC address of the network card
It is recommended to select "Automatically connect" in the general configuration
