How Do I Configure the Gateway Cable Modems? 51 Configuring TCP/UDP Port Triggers Use the Setup Advanced Settings – Port Triggers page to configure TCP/UDP port triggers. Port triggering is similar to port forwarding but is dynamic. In other words, the system does not hold the ports open indefinitely. For example, when the gateway cable modem detects outgoing data on a specific IP port number set in the “Trigger Range,” the resulting ports set in the “Target Range” will open for incoming data. If the system detects no outgoing traffic on the “Trigger Range” ports for a period of 10 minutes, the “Target Range” ports close. This is a safer method for opening specific ports for special applications, such as, video conferencing programs, interactive gaming, and file transfer in chat programs. This is safe because the ports are dynamically triggered and not held open continuously or erroneously left open by the router administrator. Therefore, these ports are not exposed and vulnerable for potential hackers to discover. If you are not familiar with the advanced settings detailed in this section, contact your cable service provider before you attempt to change any of the gateway cable modem default advanced port triggers settings. Click Port Triggers in the Advanced Settings section of the Setup page to access the Setup Advanced Settings – Port Triggers page.

How Do I Configure the Gateway Cable Modems? 67 Setup Wireless – Access Control Page Description This section describes the section headings and field descriptions of the Setup Wireless – Access Control page. Field Name Description Authentication When encryption is enabled, this selection allows you to choose one of the following authentication methods from the drop-down list: • Open System—Open system authentication allows any device to authenticate and then attempt to communicate with the WAP. Communication occurs if both devices have matching pre-configured WEP keys. Open System authentication does not provide the client with confirmation that the link has been established. This makes it more difficult for a hacker to access the network. • Shared Key—During shared key authentication, the WAP sends an unencrypted challenge text string to any device attempting to communicate with the WAP. The device requesting authentication encrypts the challenge text and sends it back to the WAP. If the challenge text is encrypted correctly, the access point allows the requesting device to authenticate. Shared key authentication provides the client with feedback when a link is denied where Open System authentication does not. • Open System or Shared Key—Either Open System or Shared Key can associate with the WAP and the WAP accepts data from wireless clients using the appropriate form of authentication. Closed Network Allows you to disable or enable the network to access by wireless clients. When ON is selected, the access point does not broadcast the SSID. The client device must be configured manually with the SSID and the MAC address of the access point in order to access with wireless network. Allow/Restrict Access Enables unrestricted access or limits access to clients listed in the Access List Access List Displays the MAC address of the clients that are allowed to access the wireless access point Connected Clients Displays the Host Name, IP Address, and Client ID of wireless clients that are connected to (associated with) the gateway modem

This setting specifies the minimal set of required data rates Control Tx Rates Displays the transmit data rates the WAP uses is a function of signal strength and signal quality. For maximum potential link speed, it is recommended that you select all control Tx rates: 1, 2 Mbps, 5.5 Mpbs, and 11 Mbps Beacon Interval Displays the time interval that the WAP uses to announce itself to remote devices. The Beacon Interval should be left at 100ms for compliance with most client cards. The Beacon Interval specifies how often packets are sent by the Access Point (AP) to synchronize a wireless network and it’s clients DTIM Interval Displays the time interval between Broadcasts/Multicast transmissions. The DTIM (Delivery Traffic Indication Message) Interval is a countdown informing the wireless clients of the next window for listening to broadcast and multicast messages. When the AP has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. AP clients hear the beacons and awaken to receive the broadcast and multicast messages. The DTIM Interval should be left at 3 ms for compliance with most client cards Fragmentation Threshold Fragmentation and ready to send (RTS) thresholds should be set equivalent to the maximum Ethernet frame size allowable on the link including overhead (1536 bytes). Lesser settings can damage data throughput as large frames could be fragmented or collisions could occur RTS Threshold The RTS/CTS threshold determines at what packet size beyond which the RTS/CTS mechanism is invoked.
