To set up a bridge interface, go to Network > Interface > Add.
Set the Type to Bridge and enter a name for the interface. The name must use the format bridgeX, where X is a number representing a non-parent interface. It is also recommended to add any notes or reminders about this particular bridge in the Description.
Under Bridge Settings, select which interfaces will be Bridge Members and then configure the remaining interface options to match your networking needs.
Every kind of network interface has common settings:
The Maximum Transmission Unit (MTU) is the largest protocol data unit that can be communicated. What the largest workable MTU size can be will change according to your available network interfaces and other physical hardware. 1500 and 9000 are standard Ethernet MTU sizes and the recommendation is to use the default 1500. The permissible range of MTU values is 1492-9216. Leaving this field blank sets the default value of 1500.
If additional tuning is needed, you can enter additional ifconfig settings in the Options
Additional aliases for the interface can also be defined:
Either IPv4 or IPv6 addresses and subnets from 1-32 can be defined. Clicking Add will provide another field for defining an IP address.
