4.3  Multiple WAN Configuration
A company uses the ZyXEL Device (Z) to connect to a cable network. They apply 
for three public IP addresses from the service provider (Cable SP) in order to 
provide web (A) and FTP (B) services to public users and Internet access for 
company users (C1 and C2). A computer from the Internet can access server A 
through IP-1 and server B through IP-2C1 and C2 connect to the ZyXEL 
Device’s LAN through a switch (S). The ZyXEL Device uses NAT to convert private 
LAN IP addresses to IP-3 for outgoing Internet packets.The following figure shows 
you an example.
