Would you like to learn how to configure the Pfsense Vlan feature? In this tutorial, we are going to show you how to perform a Vlan configuration on a Pfsense server.

• Pfsense 2.4.4-p3

Here is a list of the existent interfaces on our Pfsense server before our configuration:

• WAN - 200.200.200.200
• LAN -  192.168.1.1

In our example, we are going to create a VLAN sub-interface named OPT1 on the LAN Physical interface.

The sub-interface named OPT1 will be a member of the VLAN 10 and will use the IP address 192.168.10.1:

Here is a list of the interfaces on our Pfsense server after our configuration:

• WAN - 200.200.200.200
• LAN -  192.168.1.1
• OPT1 -  192.168.10.1

Tutorial - VLAN Configuration on Cisco Switch

Now, you need to perform the Vlan trunk configuration on the Network Switch.

In our example, we are going to show how to perform the Vlan configuration on a Cisco Catalyst Switch model 2960.

On the prompt screen, enter the administrative login information.

Use the configure terminal command to enter the configuration mode.

Copy to Clipboard

Create a new vlan, select an identification number and add a brief description.

Copy to Clipboard

Access the interface configuration mode and set the Switch port as a trunk.

Add the list of authorized Vlans to use this trunk.

Copy to Clipboard

In our example, the Switch port 40 was configured as a trunk.

The following Vlans were allowed to use this port as a trunk: 1 and 10.

Vlan 1 is the default native VLAN of Cisco Switches.

Don’t forget to save your Switch trunk configuration

Copy to Clipboard

Connect the Pfsense LAN interface to the Cisco Switch port number 40.

Traffic comming from the Pfsense LAN interface will not have VLAN tag and will be a member of the Cisco Switch native VLAN 1.

Traffic comming from the Pfsense OPT1 interface will have the VLAN tag 10 and will be a member of the Cisco Switch VLAN 10.
