To add a VLAN subinterface in Transparent mode
The VLAN ID of each VLAN subinterface must match the VLAN ID added by the IEEE
802.1Q-compliant router or switch. The VLAN ID can be any number between 1 and
4096. You add VLAN subinterfaces to the physical interface that receives VLAN-
tagged packets.
1Go to System > Network > Interface.
2Select Create New to add a VLAN subinterface.
3Enter a Name to identify the VLAN subinterface.
4Select the physical interface that receives the VLAN packets intended for this VLAN
subinterface.
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 page131 for information about virtual domains.
7Enable or disable using a Dynamic DNS service (DDNS). If the FortiGate unit uses a
dynamic IP address, you can arrange with a DDNS service provider to use a domain
name to provide redirection of traffic to your network whenever the IP address
changes.
8Configure the administrative access, MTU, and log settings as you would for any
FortiGate interface.
See “Interface settings” on page48 for more descr iptions of these settings.
9Select OK to save your changes.
The FortiGate unit adds the new subinterface to the interface that you selected.
10 Select Bring up to start the VLAN subinterface.
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.
Note: A VLAN must not have the same name as a virtual domain or zone.
