pfsense

I'm looking at getting a Netgate 2100 and configuring my home network with pfSense. I know that I can place the RT2600ac in wireless mose, but can I create an internal Wifi network and Guest wifi? Is that possible?

Has anyone set up or used an edgerouter and or pfsense/opnsense for an extra security with their rt2600ac? Looks like a pretty powerful system and was wondering if anyone had this setup using their rt2600ac as the main gateway and the edgerouter for extra firewall protection...
