NAT Server for external-to-internal access through domain
name configuration example
Network requirements
As shown in Figure 68, Web server at 10.110.10.2/24 in the internal network provides services for
external users. A DNS server at 10.110.10.3/24 is used to resolve the domain name of the Web
server. The company has two public IP addresses: 202.38.1.2 and 202.38.1.3.
Configure NAT Server to allow external users to access the internal Web server by using the domain
name.
