4. Integrated Solutions

Small Business Solutions

For small businesses, ISA 2006 can be placed between the corporate LAN and the Internet, where ISA firewall is installed more than a network card, a

Connect external (Configure public network IP address), a connection inside (Configure private network IP ground straight).

Solutions for Midsize Enterprises

In a midsize network, you can deploy to a three-host perimeter network, and in a firewall deployment in a midsize enterprise network, ISA installs three network cards,

Connect the internal, external, and DMZ areas respectively. In which the DMZ is placed to provide services to the external network of servers, such as Web, mail server.

5. Install ISA Server 2006

Components of ISA Server 2006

Arrays: A unified management approach to a set of ISA 2006 servers. All servers in the array share the same configuration

Configuration Storage Server: The configuration information that is used to store all the arrays in the enterprise is the most important part of the ISA component

ISA Server service: ISA Server running firewalls, VPNs, and caching services

ISA Server Management: Management terminals for managing enterprise and array members

Installing servers in a domain environment

6. Install ISA 2006 Client

ISA 2006 supports the following 3 types of clients:

Firewall Client (Firewall clients)

SecureNAT Client (secure network address translation clients)

Web proxies Client (Web Proxy clients)

Winsock is a network programming interface under Windows, primarily for applications that develop Windows platforms.

Gopher is an information query system on the Internet that makes the files on the Internet an index to make it easier for users to find them.

7. Configure SecureNAT Client

SecureNAT client does not need to install specific software, but the default gateway address must be set correctly

8. Configure Firewall Client

Firewall client is a computer that installs and enables Firewall Client software, and Firewall clients can send Windows user information

Provides ISA Server with body verification capabilities, preferably using firewall Client if you want to maximize the functionality of ISA

9. Configure Web Proxy Client

Web Proxy client does not need to install any software, as long as the proxy on the client computer is set to the ground of the network card in ISA Server

Address, specifying the port number at the same time
