NAT Server for external-to-internal access configuration
example
Network requirements
As shown in Figure 67, two Web servers, one FTP server and one SMTP server are in the internal
network to provide services for external users. The internal network address is 10.110.0.0/16. The
company has three public IP addresses from 202.38.1.1/24 to 202.38.1.3/24.
Configure the NAT Server feature to allow the external user to access the internal servers with public
address 202.38.1.1/24.
