hi i have a question. i have a real nice firewalll 300.00 cysco for my home, has all sorts of bells and whistles ect aplication annomaly detection ect. i also run FW and AV software. but i was wondering if i put a second router/firewall in (my old netgear web safe) wich is a very minor firewall would that make my PC and network even more secure? or would it not help. reason i ask is because i read somewhere of someone using 2 hardware firewalls. also i was wondering does a loopback adress mean your network could be compromised? i cant find the 127.0.0.0 adress since im using a new software firewall, but i know iv seen it in the past in the firewall section as an trusted adress.
