Creating a bridge

Bridges can be created using a wizard that allows you to create the interface easily.

Click on Add in the toolbar and select “Add a Bridge”. The bridge creation wizard will then appear.


The number of bridges to create depends on your firewall model.

Identifying the bridge


Name of the interface. (See warning in the introduction to the section on Interfaces)


Allows you to enter comments regarding the interface.

Address range

Fixed IP (static)

By selecting this option, the bridge will have a static address range. In this case, its IP address and the mask of the sub-network to which the bridge belongs, have to be indicated.

Dynamic IP (obtained by DHCP)

By selecting this option, the interface will be defined by DHCP. In this case, a DHCP hostname that is the name of a server for the connection (FQDN) must be indicated.


This optional field does not identify the DHCP server but the firewall. If this field has been entered and the external DHCP server has the option of automatically updating the DNS server, the DHCP server will automatically update the DNS server with the name and the IP address provided by the firewall as well as the allocated time (mandatory). This name consists of 6 bytes in hexadecimal separated by :

The period during which the IP address is kept before renegotiation must also be indicated.

Click on Next at the bottom of the screen. The bridge creation screen will appear (Step 2).

Select the interfaces for which you wish to create a bridge. The list of "Available interfaces" shows all the Ethernet and VLAN interfaces already in the configuration. At least two interfaces have to be selected in order to make a bridge, either by using arrows or by dragging and dropping between both  lists or by double-clicking on the interface. Click on Finish to confirm the creation.
