For what is is worth, and I have heard many definitions of what DMZ and Perimeter Network was, I have always used the term DMZ to describe the Segment between the Public Routers IP Interface and the Public IP Interface of the Firewall, some people configure this to be a 2 node network, one IP for the Router Interface, the interface that points to the customers firewall and the other for the firewall itself, Perimeter Network, I usually call my Service Network, this typically would be a protected subnet behind the firewall separate from your Private Business Network, typically you would publish all your public services that you offer to your customers on the Perimeter Network or which I call Service Net or Network, services like FTP, HTTP, Telnet, any Database services etc. Hope that helps -----Original Message----- From: PETER PAPE [mailto:papexpjboi@xxxxxxx] Sent: Tuesday, May 13, 2003 2:11 PM To: [ISAserver.org Discussion List] Subject: [isalist] Re: Informal Survey http://www.ISAserver.org For what it's worth, I consider the two terms to be the same thing.
