NAT DNS mapping configuration example
1. Network requirements
As shown in Figure 64, a c
ompany provides Web and FTP services to external users, and has its internal
IP addresses on the 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. It is required that:
• 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.
