Routing is what happens when different paths in a network are selected to send network traffic. One of the two routing modes is the "Network Address Translation" (NAT) and the second is the "Router". Network Address Translation (NAT) is a technique used to modify the IP address information in the IP header packet when it is in transit across a routing device.
This document explains how to configure the routing modes on RV120W and RV220W.
Note: For further details on how to configure Network Address Translation (NAT) please refer to the article One-to-One Network Address Translation (NAT) Rules Configuration on RV120W and RV220W.
Routing Mode Configuration
Step 1. Log in to the web configuration utility and choose Networking > Routing > Routing Mode. The Routing Mode page opens:
Step 2. Click a radio button corresponding to the desired routing mode from the Mode field:
• Gateway (NAT) — This is used if the Internet Service Provider (ISP) has assigned only one IP address to the user. In this case the computers that are connected through the router will have to be allotted an IP address from a private subnet (for example, 192.168.5.0).
• Router — This is used if the ISP allotted the computers in use one or multiple IP addresses. Therefore, static or dynamic routes must be configured in this case.
Note: It is important to note that when a user chooses the "Router" mode, the router will change all the settings back to default, which provides additional security to Local Area Network or the firewall settings on the firewall in NAT mode.
Step 3. Click Save to apply changes.
