Overview

VLANs (Virtual LANs) are virtual networks created on a single physical Ethernet interface (trunk interface), and each VLAN works as a standalone interface. The physical Ethernet interface works the standard way (as an untagged VLAN).

VLAN interfaces in Kerio Control can be created, edited, or removed if not needed anymore.

Kerio Control supports 802.1Q VLANs. VLAN ID should be Unique. 2 or more VLANs with the same ID would create misconfiguration issues.

Solution

Creating VLAN Interfaces

1. In Kerio Control's administration interface, go to Configuration > Interfaces.
2. Double-click the Ethernet interface.
3. In the VLAN tab, click on Add or Remove VLANs.
   
   
4. In the Configure Port dialog box:
   • Check the Create VLAN subinterfaces option.
   • Enter the VLAN IDs separated by semicolons. It can be a number between 1 and 4094. To create multiple VLANs, add less than 90 VLANs at once.
     
5. Kerio Control creates a new network interface for each VLAN. The new interfaces are added to the Other Interfaces group.
   Note: You can move VLANs to other interface groups as you see fit.
6. Double-click a VLAN interface to set the IPv4 and/or IPv6 parameters. 
   

Removing VLAN Interfaces

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

1. In Kerio Control's administration interface, go to  Configuration > Interfaces.
2. Double-click the Ethernet interface.
3. Open the VLAN tab.
4. Click on Add or Remove VLANs
   
   
5. Erase the VLAN ID from the list. To remove all VLANs, uncheck the Create VLAN subinterfaces option.
   
6. Click Apply when finished.
