Below is a list of the technology I use in this lab environment: pfSense SG-1000 running 2.4 BETA Cisco VIRL_ — Core VMWare ESXi 5.5 Update 1 Generic VLAN Aware Layer 2 Switching I will not go through the entire installation of Cisco VIRL. I am just going to go through what I do in my personal environment to allow the FLAT & FLAT2 networks to be routable to the world.
