Firewall Settings

Overview

This section explains how to configure your Router’s firewall security features. The Router’s firewall security

settings allow you reduce the risk of unauthorized access to your network by prohibiting certain types of

inbound and outbound network traffic and by allowing you to configure specific firewall rules.

To change your firewall security level, click the option next to the desired security setting. Next, click

Apply

to

allow the changes to take effect.

High security level only allows basic Internet functionality. Only Mail, News, Web, FTP, and

IPSEC are allowed. All other traffic is prohibited.

Like High security, Medium security only allows basic Internet functionality by default.

However, Medium security allows customization through NAT configuration so that you can

enable the traffic that you want to pass.

Low security setting will allow all traffic except for known attacks. With Low security, your

Gateway is visible to other computers on the Internet.
