Chapter 6: Proxy Server in Internet and Intranet Designs
CHAPTER 6 Proxy Server in Internet and Intranet Designs
About This Chapter
With the explosive expansion of the Internet, most of the networks you’ll design will include Internet connectivity. These networks won’t only require connectivity to the Internet, but also isolation from unauthorized Internet-based users. The majority of your designs will also share the Internet connection with potentially thousands of users who access common Internet sites and files. Some of these networks might be based on Internetwork Packet Exchange (IPX), but require Internet connectivity. Many networks providing Internet connectivity for the first time use private Internet Protocol (IP) addressing schemes. Your networking services designs must provide connectivity for these networks.
You can use Microsoft Proxy Server 2.0 to provide Internet connectivity for IP and IPX-based networks. Proxy Server can keep locally cached copies of commonly accessed Internet sites and files to improve Internet performance. Proxy Server also provides network address translation to facilitate private IP addressing schemes. You can secure the Internet connection by using Proxy Server to restrict the Internet sites that users can access and to prevent unauthorized access by Internet users.
This chapter answers questions such as:
- In what situations are the Internet connectivity services provided by Proxy Server appropriate for your design?
- Which client computer operating systems and software can connect to the Internet through Proxy Server?
- How can you restrict private network users’ access to Internet Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP) sites?
- How can you restrict Internet users’ access to private network resources?
- How can you ensure that Internet connectivity is always available to private network users and Internet users?
- How can you improve the performance of accessing private network resources or Internet resources?
Before You Begin
Before you begin, you must have an overall understanding of
- Network technologies (including Ethernet, Token Ring, hubs, switches, and concentrators)
- Common transport protocol configuration for Internet Protocol (IP) (such as IP address, subnet mask, or default gateway for IP)
- IP routed networks (including subnets, network segments, routers, and IP switches)
- IPX routed networks (including network segments, routers, and IPX to IP gateways)
- Proxy server technologies (including Web content caching, protocol filtering, or domain filtering)
- Network address translation between public and private IP addressing schemes
