Adding VLAN subinterfaces

System network

 

 

5Enter the VLAN ID that matches the VLAN ID of the packets to be received by this VLAN subinterface.

6Select the virtual domain to which to add this VLAN subinterface.

See “System virtual domain” on page 131 for information about virtual domains.

7Select the name of a zone if you want this VLAN subinterface to belong to a zone.

You can only select a zone that has been added to the virtual domain selected in the previous step. See “Zone” on page 58 for information about zones.

8Configure the VLAN subinterface settings as you would for any FortiGate interface. See “Interface settings” on page 48.

9Select OK to save your changes.

The FortiGate unit adds the new VLAN subinterface to the interface that you selected in step 4.

To add firewall policies for VLAN subinterfaces

Once you have added VLAN subinterfaces you can add firewall policies for connections between VLAN subinterfaces or from a VLAN subinterface to a physical interface.

1Go to Firewall > Address.

2Select Create New to add firewall addresses that match the source and destination IP addresses of VLAN packets.

See “Address” on page 198.

3Go to Firewall > Policy.

4Add firewall policies as required.

VLANs in Transparent mode

In Transparent mode, the FortiGate unit can apply firewall policies and services, such as authentication, protection profiles, and other firewall features, to traffic on an IEEE

802.1VLAN trunk. You can insert the FortiGate unit operating in Transparent mode into the trunk without making changes to your network. In a typical configuration, the FortiGate internal interface accepts VLAN packets on a VLAN trunk from a VLAN switch or router connected to internal VLANs. The FortiGate external interface forwards tagged packets through the trunk to an external VLAN switch or router which could be connected to the Internet. The FortiGate unit can be configured to apply different policies for traffic on each VLAN in the trunk.

For VLAN traffic to be able to pass between the FortiGate Internal and external interface you would add a VLAN subinterface to the internal interface and another VLAN subinterface to the external interface. If these VLAN subinterfaces have the same VLAN IDs, the FortiGate unit applies firewall policies to the traffic on this VLAN. If these VLAN subinterfaces have different VLAN IDs, or if you add more than two VLAN subinterfaces, you can also use firewall policies to control connections between VLANs.
