Adding VLAN subinterfaces to a virtual domain

Use the following procedure to add VLAN subinterfaces to a virtual domain. You must add at least two VLAN subinterfaces to each virtual domain. In most configurations a virtual domain is used to send VLAN-tagged packets received at one FortiGate physical interface to another FortiGate physical interface (for example, from the internal interface to the external interface). For this to occur, you must add VLAN subinterfaces to the receiving and sending physical interfaces (for example, to the internal and external interfaces.

To add VLAN subinterfaces to a virtual domain

1Go to System > Network > VLAN.

2Select the Virtual Domain to add the VLAN subinterface to.

3Select New to add a VLAN subinterface.

4Type a Name for the VLAN subinterface.

5Select the interface to associate the VLAN subinterface with.

The VLAN subinterface must be added to the FortiGate interface that receives the VLAN-tagged packets.

6Enter a VLAN ID for the VLAN subinterface.

The VLAN ID can be any number between 1 and 4095.

7Optionally, select a zone to add the VLAN subinterface to a zone.

To add a zone to a virtual domain, see “Adding zones to virtual domains” on page 150.

8Select OK to add the VLAN subinterface.

9Repeat these steps to add more VLAN subinterfaces to the virtual domain.

To configure management access and traffic logging for VLAN subinterfaces

1Go to System > Network > Management.

2Configure management access as required for the VLAN subinterfaces that you have added.

You can select HTTPS, PING, SSH, SNMP, HTTP, or TELNET.

3Select Log to configure traffic logging for the VLAN subinterfaces that you have added.

Adding zones to virtual domains

Add zones to a virtual domain to group together related VLAN subinterfaces. Use zones to simplify firewall policy creation if you have many VLAN subinterfaces in a virtual domain. For more information about zones, see “Configuring zones” on page 137. Use the following procedure to add a zone to a virtual domain.
