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-2. C1 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.
