Example for Configuring NAT

7.1.1 Network Requirements

A company has two departments: Market Department and RD department. Each
department is assigned to an individual subnet. The company has the following
requirements:
1) The two departments need to access the internet via the same gateway router.
2) The company has a web server which needs to be accessed by the users on the
internet.

Market Department
172.16.20.0/24

7.1.3 Configuration Scheme

To meet the first requirement, add Multi-nets NAT entries for the two departments
respectively on the gateway router, thus the router can translate and deliver packets
whose source IP addresses are in different subnets from the router's LAN IP segment.
Then configure static routing on the gateway router to make sure the router know where to
deliver the packets to IP addresses in different subnets (172.16.10.0/24, 172.16.20.0/24).
