Recently, I moved from the northern New Jersey area to Cherry Hill which is about 3 miles from Philadelphia. There will be an unmanaged hub between the cable modem and border router, which will provide a sniffing point for the IDS sensor.

Modem –> Unmanaged Hub –> Cisco 2651 Border Router –> Linux based Firewall –> Switch –> Boxen
(Dual OC-192’s and Dual OC-48’s) — I’ll settle for this until I can afford a few OC-768 pipes 😛
