Technical requirements

To work through the examples in this chapter, you will need a working pfSense system with at least one optional interface. To actually implement a working VLAN, you will need a managed switch as well. The TP-Link TL-SG108E, which is used for the first example in this chapter, is an example of a relatively low-cost SOHO managed switch. Cisco managed switches are often found in corporate environments and are generally more expensive, although they can often be purchased used at a reasonable price.
