WAN IP Address
The WAN IP address is an IP address for the LTE Device, which makes it accessible from an outside
network. It is used by the LTE Device to communicate with other devices in other networks. It can
be static (fixed) or dynamically assigned by the ISP each time the LTE Device tries to access the
Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and
DNS server IP address(es).
APN
Access Point Name (APN) is a unique string which indicates an LTE network. An APN is required for
LTE stations to enter the LTE network and then the Internet.
CAPWAP
The LTE Device supports CAPWAP. This is ZyXEL’s implementation of the CAPWAP protocol (RFC
5415).
The CAPWAP dataflow is protected by Datagram Transport Layer Security (DTLS).
The following figure illustrates a CAPWAP wireless network. You (U) configure the AP controller (C),
which then automatically updates the configurations of the managed APs (M1 ~ M4).

CAPWAP Network Example
Note: The LTE Device can be a standalone AP (default), a CAPWAP managed AP, or a
CAPWAP AP controller.
CAPWAP Discovery and Management
The link between CAPWAP-enabled access points proceeds as follows:

An AP in managed AP mode joins a wired network (receives a dynamic IP address).
