Chambers has his eye on everything... The Pix wasnt developed by cisco by the way, the technology was aquired. This is Cisco's Buisness plan it seems.

I understand what you are saying, however I dont understand how stopping outbound connections on your Eneterprise edge will help anything Within your AS. Can you explain?

Worm propogation should be stopped at the "Access layer" of your network not at the core, I would suspect most Enterprises have there WAN links at the core.

Anyway.. Every Engineer has a different way at looking at things.

Whats a firewall?

John,

When you're running wire and you have to go through a wall that is completely sealed to keep smoke and fire out, that's a firewall.

Just kidding, I know you know about that. A network/computer firewall is designed to do the same thing. It keeps all of the bad stuff on the other side of the wall (internet) from coming into your room (network).

I just couldn't resist, Test OK did it and I hurt myself laughing. Thought I'd try it myself before the post went nuclear. Instead of HOT TOPIC is was headed for HOT-HEAD Topic.

Come on guys!!!!!
Everyone knows what a firewall is!!!!

Its that thing you run into when pulling cables that stops you from seeing the other side so you have to poke a hole through it to get your cable through. No we know who doesnt seal the penetrations.

All the firewalls I have seen have all looked the same....Sheetrock partially painted and taped that goes all the way to the ceiling.

How do I identify the difference between a PIX, SONIC, or LINKSYS firewall?

DEuhh! eeert! deeert!

Now that's funny. :rofl: :rofl: giddy up

My two bits is that no matter how small or large any network is, when a PC has access to the Internet there should be protection from the outside world. Viruses, phishing, scams and such forth are existent and everyday more and more "Identity Theft" is accomplished from an improperly protected network. The lack of a true hardware firewall gateway straddling the infrastructure prior to the router which is prior to the switch connecting all PC's together is only trouble. Sonicwall is a good product and the Linksys I can never keep working long enough. I would suggest everyone taking a look at the WatchGuard product line which has excellent performance and is lower in price than the Sonicwall. Linksys and CISCO PIX I avoid, D-Link and Netgear and not worth the trouble

Just say screw it and get an old PC, throw in 2 NIC cards instead of one, load a good linux based firewall distro, configure IPChains and go for it, no need for the expen$ive sonic stuff or the cheap Linksys(low end Cisco) stuff either. Just plug it into a 10/100 switch and go to town. This method is more cost efficient and much much more configurable. If you wish to have a DMZ port you will however need to throw in a third NIC card into the firewall PC. Thanks for all the laughs reading thread, I love a good flame war!

The flames were put out back in Feb., but I still see a few puffs of smoke...

And like I said above,
