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