7.1.2 What You Need to Know

The following terms and concepts may help as you read this chapter.
WAN IP Address
The WAN IP address is an IP address for the Zyxel Device, which makes it accessible from an outside
network. It is used by the Zyxel Device to communicate with other devices in other networks. The ISP
dynamically assigns it each time the Zyxel Device tries to access the Internet.
APN
Access Point Name (APN) is a unique string which indicates a cellular network. An APN is required for
cellular stations to enter the cellular network and then the Internet.
IP Passthrough
The Zyxel Device supports IP passthrough which allows Internet traffic to go to a LAN device behind the
Zyxel Device without going through Network Address Translation (NAT). Your LAN device will have the
public IP assigned by the ISP. Use this for applications that require a direct connection to the Internet
using a public IP address, such as gaming or web server.
Note: The NAT function and DHCP pool are restricted for WAN connection that has IP
Passthrough enabled.
