Network requirements

As shown in Figure 28, a company provides Web and FTP services to external users, and uses internal

IP network segment 10.110.0.0/16. The IP addresses of the Web and FTP servers are 10.110.10.1/16 and

10.110.10.2/16 respectively. The company has three public addresses 202.38.1.1/24 through

202.38.1.3/24. The DNS server is at 202.38.1.4/24.

• The public IP address 202.38.1.2 is used to provide services to external users.

• External users can use the public address or domain name of internal servers to access them.

• Internal users can access the internal servers by using their domain names.
