Advanced, Filtering, Setting Up Filters

Instant Broadband™ Series

Advanced

The following instructions are for advanced users or users whose setup needs require special configuration. When you click the Advanced tab, you will be able to set up these features. There are seven additional tabs available.

•Filters - Block specific internal users from Internet access and enable Virtual Private Network (VPN) sessions.

•Forwarding - Sets up public services on your network.

•Dynamic Routing - Sets up the Gateway so it will automatically adjust to physical changes in the network’s layout.

•Static Routing - Sets up static routes needed when network information must travel to a specific host or network.

•DMZ Host - Allows one local user to be exposed to the Internet for use of special-purpose services such as online gaming or videoconferencing.

•Firewall - Allows the Gateway to use Stateful Packet Inspection (SPI) to auto- matically detect and block Denial of Service (DoS) and hacking attempts.

•Link Test - Allows an advanced user or technician to perform advanced diag- nostics of the ADSL Gateway and perform connectivity tests.

Filtering

Important: This is an Advanced Function. No changes should be made to this tab without a thorough understanding of network concepts.

Filters block specific internal users from accessing the Internet and enable Virtual Private Network (VPN) sessions. You can set up filters by using IP addresses, network port numbers (or a range of ports), or MAC addresses.

Setting Up Filters

•Filtered Private IP Range To set up a filter using IP addresses, enter the range of IP addresses you wish to filter in the IP address fields. Users who have filtered IP addresses will not be able to access the Internet at all. If you only want to filter one IP address instead of a range of IP addresses, enter the same value into both fields.
