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.
