    Configuring the Firewall Overview The DW4020 has the capability to "drop" or block certain kinds of IP packets from reaching your local area network (LAN) from the Internet. This can help protect the computer(s) on your LAN from receiving undesired or harmful traffic via the Internet.
  • Page 76 Please note that the DW4020 firewall is provided to you at minimal charge. ACCORDINGLY, YOU AGREE THAT NEITHER HUGHES NETWORK SYSTEMS, INC, HUGHES ELECTRONICS CORPORATION OR ANY OF THEIR RESPECTIVE AFFILIATES (COLLECTIVELY "HUGHES") HAS MADE NO EXPRESS WARRANTIES, ORAL OR WRITTEN, TO YOU REGARDING THE FIREWALL SOFTWARE AND THAT THE FIREWALL SOFTWARE IS BEING PROVIDED TO YOU "AS IS"...

  • Page 77: Firewall Configuration

    Firewall To configure the firewall, you can define up to 10 "rules" using the Firewall screen on the User Interface in the DW4020. If the control Configuration Configuration information in an incoming packet matches any of the defined rules, the DW4020 drops the packet.

  • Page 78: Deleting Rules

    Use the drop down menu to specify that one Port Number or Protocol ID. or the other of these fields be checked for each rule that you define. See below for more information on the standard Internet values used for port numbers and protocol IDs.

  • Page 79: Port Numbers And Protocol Ids

    Port Numbers and The Internet Assigned Numbers Authority (IANA) maintains the official list of Port Numbers and Protocol IDs used on the Internet. You can see this list at: Protocol IDs http://www.iana.org/numbers.html. Some common port numbers that you might want to use in firewall rules are shown in Table 1.

  • Page 80: Sample Firewall Configuration

    Sample Firewall Figure 2 shows a sample firewall configuration. This single rule blocks all incoming File Transfer Protocol (FTP), Telnet, and Domain Name Server Configuration (DNS) requests that originate from any IP address. These protocols are some of the most common ones used to attack computers on the Internet. This rule will not block FTP sessions, Telnet sessions, or DNS requests (and corresponding responses) that originate from computers on your LAN through the DW4020 to the Internet.
