Connecting to the Internet: A Practical Guide about LAN-Internet Connectivity





System and network administrators faced with the challenge of building
and maintaining permanent LAN-to-Internet connections are often in
need of additional information in order to complete this complex task.
This practical handbook is a guide to the entire process of connecting a
private network to the Internet and then maintaining that connection.

Comprehensive yet succinct, Connecting to the Internet provides
essential information without the burden of extraneous detail. Using a
step-by-step approach, this book covers the processes of planning,
designing, implementing, and maintaining an effective and secure
LAN-to-Internet connection--from TCP/IP essentials, to choosing the
most appropriate Internet Service Provider, to setting up a firewall.

Specifically, you will find coverage of:

TCP/IP essentials and standard Internet service protocols, such as DNS, FTP, Mail, News, Telnet, the Web, and SSL
Criteria for choosing an Internet Service Provider, including connection capacity, installation services, Web hosting, security, VPNs, remote access, multicast, knowledge services, and pricing
Circuitry and equipment configuration for your WAN
Security technologies--packet filters, circuit proxies, application gateways, network address translation, firewalls, vendors, security policies, and auditing
Network design and equipment selection
Staging and testing the design, including how to run routing diagnostics and security testing
Implementing the new connection, going live with the ISP, and troubleshooting the WAN
Managing the LAN-Internet connection, with discussions on security breaches, usage monitoring, and performance issues

Each technical chapter contains checklists to help you track critical steps
in the process. In addition, experienced-based tips throughout the book
will keep you from falling into expensive and time-consuming pitfalls.For network administrators, one of the most intriguing--albeit challenging--moves is the connection of their local area network to the Internet. Connecting to the Internet: A Practical Guide to LAN-Internet Connectivity specifically addresses this important evolutionary move with very concrete suggestions and background material.

This brief book opens with a detailed look at the protocols involved in TCP/IP networking. The section includes information on IP, UDP, NNTP, FTP, and DNS--all key elements of Internet-based networks, but often not present in legacy LANs. Next, author Andrew Ward discusses how to select an Internet Service provider--a chapter that discusses service levels, bandwidth availability, and pricing.

The book continues with chapters on building a Wide Area Network infrastructure and security. The latter chapter covers important topics such as firewalls, encryption, and Virtual Private Networks (VPNs). After presenting this background material, the author steps back and details the procedures involved in moving your network to the Net. He also includes short chapters on how to test your new network. The last chapter, which covers management of your Internet-LAN system, is a bit too brief.

Few networking projects are more daunting than moving a working LAN to a new Internet-connected WAN model. This handy how-to contains loads of helpful information. --Stephen W. Plain
