Configuring VLANs

VLAN support in Kerio Control

VLANs (Virtual LANs) are virtual networks created on a single physical Ethernet interface (trunk interface).

Kerio Control supports 802.1Q VLANs.

Each VLAN works as a standalone interface. The physical Ethernet interface works the standard way (as an untagged VLAN).

Creating VLAN interfaces

To define new VLANs:

  1. Go to section Configuration > Interfaces.
  2. Double-click the Ethernet interface.
  3. Open the VLAN tab.
  4. Click Add or Remove VLANs...
  5. Check Create VLAN subinterfaces.
  6. Type VLAN IDs separated by semicolons. VLAN ID is a number between 1 and 4094. To create multiple VLANs, add less than 90 VLANs at once. Kerio Control creates a new network interface for each VLAN. The new interfaces are added in the Other Interfaces group.
  7. You can move VLANs to other interface groups.
  8. Double-click a VLAN interface to set the IPv4 and/or IPv6 parameters.

Now you can use the VLAN interface in traffic rules.

Removing VLAN interfaces

To remove a VLAN, remove the VLAN ID from the trunk interface:

  1. Go to section Configuration > Interfaces section.
  2. Double-click the Ethernet interface.
  3. Open the VLAN tab.
  4. Click Add or Remove VLANs...
  5. Delete the VLAN ID from the list. To remove all VLANs, uncheck the Create VLAN subinterfaces option.

The VLAN interface is removed from the Interfaces section and from all traffic rules.
