Network Address Translator: NAT

Introduction

The purpose of this document is to describe Crestron’s implementation of the

Network Address Translator (NAT) with respect to a 2-Series Control system with

the optional Z-Bus card (C2ENET-2) installed.

Features/Functions of Crestron NAT

Crestron Network Address Translation (NAT) is a method of connecting multiple

Crestron IP devices and other IP enabled AV devices on an internal network (LAN)

to access the Internet (WAN) using one static IP address.

NOTE: The NAT throughput (from LAN B to LAN A) should not exceed 1Mbps

(megabits per second). Crestron does not recommend use of high-volume streaming

output devices such as IP-based codecs.
