Introduction

The configuration of Network Address Translation (NAT) is described in the chapters below.

Network Address Translation (NAT) is a function on your device for defined conversion of source and destination addresses of IP packets. If NAT is activated, IP connections are still only allowed by default in one direction, outgoing (forward) (= protective function). Exceptions can be configured in the NAT Configuration menu.

You have a permanent 2-Mbps connection to the Internet with 8 IP addresses. Your Ethernet interface ETH is connected to the access router. This has the IP address 62.10.10.1/29 , whereas the remaining IPs from 62.10.10.2 to 62.10.10.6 are entered on Ethernet interface ETH.

You configure NAT enables for accessing your gateway over HTTP. You also want to access your terminal server and the corporate web server over the Internet.

Configuration in this scenario is carried out using the GUI™ (Graphical User Interface).
