    Exclamation A Guide to Hardware Firewalls....

    There is a lot of threads that are asking about hardware firewalls, so I thought a thread covering the topic was the best way to reply. There is an independent company that tests and certifies firewalls.This is their site. It will tell you everything from what is a firewall, what criteria is needed, what are the requirements, and what products has made their certification. http://www.icsa.net/html/communities...ls/index.shtml
    Their criteria is strict and their testing very detailed and thorough. Their certifications set the industry standard. Just follow some links in there to learn.
    This is the list of what products have that have met and maintain their certifications; http://www.icsa.net/html/communities...rs/index.shtml
    This is a comparison of firewalls listing different types of info; http://www.practicallynetworked.com/...uter_chart.htm
    These are some reviews; http://www.practicallynetworked.com/...dex_router.htm http://computers.cnet.com/hardware/0...-634784-634624 http://www.speedguide.net/reviews/index.shtml
    There is alot of sites that have done reviews of individual products, however they would be more for ease of setup type info, not really tech data. If anyone has an interest in a particular product, let me know and I will post some specific links for you.
    Keep in mind that a router is not neccessarily a firewall. A lot of them rely upon NAT which only hides you, they can do nothing if someone knows that you are there. On Cisco, unfortunately I couldn't find any type of real details pertaining to how secure their systems are. I found the wording to be somewhat confusing and vague on the actual descriptions of their products and nothing to back it up.
    Some of you have asked what firewall I purchased, here you go... http://www.3com.com/products/dsheets/400526_01.html#2
    This site also tells you about DMZ, if you run a server, read about it here.
    This is the results of my firewalls testing and certifications; http://www.icsa.net/html/communities...a_report.shtml

    A Linksys router is not really a true firewall. It uses NAT (Network Address Translation) to hide your IP from the net. It will allow you to stealth tests, but it is not a true firewall...

    Cool

    Once Linux is on my box I am gonna take that Linky and hook my Linux box to the WAN port, the other computer ot the LAN port...and have fun....then all the holes will be kept to myself so I can toy with other Linky's, ....(remember the DMZ one everyone......closed port instead of stealth was reported, solved by setting false DMZ host)

    thanks for the informative post but when you say "Keep in mind that a router is not neccessarily a firewall. A lot of them rely upon NAT which only hides you, they can do nothing if someone knows that you are there."

    if it hides my ip, how does the bad guy get my ip ("know i'm out there" if i'm using using the nat router? sorry for the lamer q here but just trying to learn. thanks for any help. rookie
