IP Link Installation Manual
Wide Area Network (WAN)
As the term implies, a wide area network spans a large physical distance. A WAN like the Internet
spans most of the world. A WAN is a geographically-dispersed collection of LANs. A network device
called a router connects LANs to a WAN. In IP networking, the router maintains both a LAN address
and a WAN address.
In addition, you will notice that there are two constants in LAN and WAN network topologies:
•
Assigning the IP address for communication between the controllers and EntraPass
• Managing both types of IP addresses, static and dynamic
We recommend that you carefully read the following section in order to correctly select the
configuration that matches the network architecture where you will install the IP Link.
LAN Configurations
There are two LAN configurations for the IP Link:
Note: Kantech recommends the use of a Static or Reserved DHCP IP address for the IP Link and the
Gateway.
Static IP Addressing
You will use this type of configuration in an environment where the Network Administrator will
determine the IP address for communication between EntraPass and the IP Link. We recommend
using the EntraPass application to configure the IP Link. The other 2 methods, the KT-Finder and the
Web Configuration Page, can be used when the PC has no EntraPass application running.
Reserved DHCP IP Addressing
You will use this type of configuration in an environment where the customer DHCP server assigns the
IP address automatically to the IP Link. Additionally, the IP address of the IP Link will have to remain
the same, which is called Reserved DHCP. We recommend using the EntraPass application to
