Bridging
• A bridge cannot include multiple VLANS on the same switch.
• If a DHCP server is used for a connection, and the bridge you are adding uses a static IP, then the settings
are incompatible. DHCP must be disabled or deleted.
To add a bridge
1
From the Network Setup menu, click Network Setup and select the Connections tab.
2
From below the main Connections table, select Bridge from the list and click Add. The Bridge
Configuration tab appears (
Figure 92 ).

If you want to transfer the IP address settings of an existing network connection to the bridge interface,
select it from the Existing Interface Configuration list. Otherwise, select None.
Note: Since the appliance automatically directs network traffic, hosts on either side do not need to specify this
IP address as a gateway to the networks connected to the bridge. It is not so important which IP address you
choose to assign to the bridge interface; it is primarily used by hosts on either side of the bridge only to
connect to the Management Console of the appliance. Specific routes are still required to reach networks that
are not being bridged.
4
Click Next. If you selected an existing interface, the Edit Bridge Configuration page appears. Skip to
Step 5 (page 96) . If you selected None, the Direct Connection Settings page appears ( Figure 93 ).
