Example Configurations

The following section provides configuration examples for two common PIX 515E configuration

scenarios: hosting a web server on a DMZ network and establishing a site-to-site VPN connection with

other business partners or remote offices. Use these examples to set up your network. Substitute

network addresses and apply additional policies as needed.

DMZ Configuration

A demilitarized zone (DMZ) is a neutral zone between private (inside) and public (outside) networks.

A DMZ allows you to have a presence on the public Internet, while protecting private network

resources that are accessed by users on the public Internet; for example, mail servers or web servers.

The illustration below shows a sample network topology that is common to most DMZ

implementations using the PIX 515E, in which the web server is on the DMZ interface. HTTP clients

from the inside and the outside networks are able to access the web server securely.

In the illustration below, an HTTP client (10.10.10.10) on the inside network initiates HTTP

communications with the DMZ web server (30.30.30.30). HTTP access to the DMZ web server is

provided for all clients on the Internet; all other communications are denied. The network is

configured such that the range of available IP addresses on the DMZ interface are between

30.30.30.50–30.30.30.60. There are two publicly routable IP addresses available, one for the

PIX 515E outside interface (209.165.156.10) and one for the translated DMZ server

(209.165.156.11). Because the DMZ server is located on a private DMZ network, it is necessary to

translate its private IP address to a public (routable) IP address. This public address allows external

clients HTTP access to the DMZ server as though it was located on the Internet. Use PDM to quickly

configure your PIX 515E for secure communications between HTTP clients and web servers.
