With this configuration, all HTTP (Web) TCP traffic on port 8000 from any IP Address from the WAN side will be redirected through the firewall to the Internal Server (192.168.0.100) on port 80.

NOTE: This configuration is useful because you don’t have to reconfigure your web server to accept traffic on a different port, you can do this configuration on the Gateway.

FIREWALL

The Gateway provides a stateful inspection firewall (SPI), which is designed to protect against Denial of Service (DoS) attacks. Its purpose is to allow a private local area network (LAN) to be securely connected to the Internet. To provide a flexible solution, the firewall section has the following features:

Firewall Enable/Disable

To access the Security Settings configuration page, on the Side Navigation bar, click on [Firewall] link.

To enable this feature, check the [Enable Firewall Module] checkbox.

Access Control

The Access Control section allows the setting of two types of rules: enable access to services on your public LAN network from the Internet or to block services on the private LAN from accessing the Internet. Access Rules can be configured to a specific LAN IP Address or a range of LAN IP Address’s.

To access the Access Control configuration page, on the Side Navigation bar, click on [Firewall] link and then click on the [Access Control] link.

To enable this feature, check the [Enable Access Control] checkbox.

There are 2 sections in that can be configured for Access Control Rules.

The first section is used to configure the Access Rules for the Public LAN from the Internet. These rules will enable services on the public LAN to be accessed by the Internet.
