@EddieA:
I currently run pfSense as a VM on ESXi.
My cable modem goes to one NIC, on the ESXi server, where the pfSense WAN is the only VM connected. The pfSense LAN goes to a separate virtual switch, where other VMs connect, and also to a second NIC, and a physical switch, where the rest of my network is hooked up.
I'm quite happy with this setup, and it works perfectly well. But, as can be seen in another post here, I just picked up an HP Thin Client, where I'm going to run pfSense, to sit between the cable modem and "relegate" the ESXi server to being just another machine on my network.
Cheers.
This is what I plan to do. Maybe in the future run a physical box. Are you using this method as solely a firewall? Any other features?
