This recipe describes how to configure the Local Area Network (LAN) internal interface of our firewall.
Getting ready
The LAN interface is used to connect your devices to a secure internal network. A properly configured LAN interface is required.
How to do it...
Browse to Interfaces | LAN.
Check Enable Interface.
Choose an address configuration Type.
Enter an IP address and subnet mask. Leave Gateway set to None.
Ensure Block private networks and Block bogon networks are unchecked.
Save the changes.
How it works...
You've just defined your first internal network. If you've been performing the recipes in order, you've now met the minimum requirements for a fully-functioning firewall! You've defined one external network (WAN) and one internal network (LAN). You can now define the rules and relationships to regulate traffic between the two.
There's more...
You can now connect a switch to the LAN interface on your pfSense machine. This will allow you to connect multiple computers to your LAN network.
