Chapter 1 Getting Started

Using PIX Firewall in a Small Office, Home Office Environment

This section describes features provided by the PIX Firewall that support its use in a small office, home

office (SOHO) environment. It includes the following topics:

• Using the PIX Firewall as an Easy VPN Remote Device, page 1-19

• PPPoE, page 1-19

• DHCP Server, page 1-19

• DHCP Client, page 1-20

For information about configuring the features in this section, refer to Chapter 4, “Using PIX Firewall

in SOHO Networks.”

Using the PIX Firewall as an Easy VPN Remote Device

You can use a PIX 501 or PIX 506/506E running PIX Firewall Version 6.2 or higher as an Easy VPN

Remote hardware client when connecting to an Easy VPN Server, such as a Cisco VPN 3000

Concentrator or another PIX

Firewall. An Easy VPN Remote hardware client allows hosts running on

the LAN behind the PIX

Firewall to connect to an Easy VPN Server without individually running any

VPN client software.

PPPoE

Point-to-Point Protocol over Ethernet (PPPoE) combines two widely accepted standards, Ethernet and

the Point-to-Point Protocol (PPP), to provide an authenticated method of assigning IP addresses to client

systems. PPPoE clients are typically personal computers connected to an ISP over a remote broadband

connection, such as DSL or cable service. ISPs deploy PPPoE because it provides a method of supporting

high-speed broadband access using the existing remote access infrastructure and that provides superior

ease of use to customers.

PIX Firewall Version 6.2 or higher provides PPPoE client functionality. This lets small office, home

office (SOHO) users of the PIX

Firewall connect to ISPs using DSL modems.

Note The PIX Firewall PPPoE client can only be enabled on the outside interface.

By using PPPoE, ISPs can deploy DSL without changing their existing infrastructure, which is typically

based on the use of PPP over dial-up connections.

DHCP Server

Dynamic Host Configuration Protocol (DHCP) is a protocol that supplies automatic configuration

parameters to Internet hosts. This protocol has two components:

• Protocol for delivering host-specific configuration parameters from a DHCP server to a host (DHCP

client)

• Mechanism for allocating network addresses to hosts
