Reference Manual for the ADSL Modem Wireless Router DG834G The time it takes to establish a wireless connection can vary depending on both your security settings and placement. WEP connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook computer. Implement Appropriate Wireless Security Note: Indoors, computers can connect over 802.11g wireless networks at a maximum range of up to 300 feet.
Reference Manual for the ADSL Modem Wireless Router DG834G • WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption will block all but the most determined eavesdropper. This data encryption mode has been superseded by WPA-PSK and WPA2-PSK. • WPA-802.1x, WPA2-802.1x. Wi-Fi Protected Access (WPA) with user authentication implemented using IEE 802.1x and RADIUS servers. • WPA-PSK (TKIP), WPA2-PSK (AES).
Reference Manual for the ADSL Modem Wireless Router DG834G Understanding Wireless Settings To configure the Wireless interface of your modem router, click the Wireless Settings link in the Setup section of the main menu. The Wireless Settings menu will appear, similar to that shown below: Figure 4-2 4-4 Wireless Configuration v1.
Reference Manual for the ADSL Modem Wireless Router DG834G The following parameters are in the Wireless Settings menu: • Wireless Network. — Name (SSID). The Service Set ID, also known as the wireless network name. Enter a value of up to 32 alphanumeric characters. The same Name (SSID) must be assigned to all wireless devices in your network. The default SSID is NETGEAR, but NETGEAR strongly recommends that you change your network Name to a different value. Note: This value is case sensitive.
Reference Manual for the ADSL Modem Wireless Router DG834G — Wireless Isolation. If enabled, Wireless Stations will not be able to communicate with each other or with Stations on the wired network. This feature should normally be disabled. • Wireless Station Access List. — By default, any wireless computer that is configured with the correct wireless network name or SSID will be allowed access to your wireless network.
Reference Manual for the ADSL Modem Wireless Router DG834G Table 4-1. Wireless Security Options (continued) Field Description WPA-PSK (TKIP), WPA2PSK (AES) WPA Pre-Shared-Key (Wi-Fi Protected Access Pre-Shared Key) uses a pre-shared key to perform the authentication and generate the initial data encryption keys. Then, it dynamically varies the encryption key. WPA-PSK (TKIP) implements most of the IEEE 802.
Reference Manual for the ADSL Modem Wireless Router DG834G 5. Set the Channel. The default channel is 11. This field determines which operating frequency will be used. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby wireless router or access point.

Reference Manual for the ADSL Modem Wireless Router DG834G Configuring Basic Firewall Services Basic firewall services you can configure include access blocking and scheduling of firewall security. These topics are presented below. Blocking Keywords, Sites, and Services The modem router provides a variety of options for blocking Internet based content and communications services. With its content filtering feature, the ADSL Modem Wireless Router prevents objectionable content from reaching your PCs.
Reference Manual for the ADSL Modem Wireless Router DG834G 2. Select the Block Sites link of the Security menu. Figure 5-3 3. To enable keyword blocking, select one of the following: • Per Schedule—to turn on keyword blocking according to the settings on the Schedule page. • Always—to turn on keyword blocking all of the time, independent of the Schedule page. 4. Enter a keyword or domain in the Keyword box, click Add Keyword, then click Apply.
Reference Manual for the ADSL Modem Wireless Router DG834G You can specify one trusted user, which is a computer that will be exempt from blocking and logging. Since the trusted user will be identified by an IP address, you should configure that computer with a fixed IP address. 7. Click Apply to save your settings. Firewall Rules Firewall rules are used to block or allow specific traffic passing through from one side of the router to the other.
Reference Manual for the ADSL Modem Wireless Router DG834G To access the rules configuration of the DG834G v4, click the Firewall Rules link on the main menu, then click Add for either an Outbound or Inbound Service. Figure 5-4 • • • To edit an existing rule, select its button on the left side of the table and click Edit. To delete an existing rule, select its button on the left side of the table and click Delete.
Reference Manual for the ADSL Modem Wireless Router DG834G Inbound Rules (Port Forwarding) Because the DG834G v4 uses Network Address Translation (NAT), your network presents only one IP address to the Internet, and outside users cannot directly address any of your local computers. However, by defining an inbound rule you can make a local server (for example, a Web server or game server) visible and available to the Internet.
Reference Manual for the ADSL Modem Wireless Router DG834G The parameters are: • Service—From this list, select the application or service to be allowed or blocked. The list already displays many common services, but you are not limited to these choices. Use the Services menu to add any additional services or applications that do not already appear. • Action—Choose how you want this type of traffic to be handled.
Reference Manual for the ADSL Modem Wireless Router DG834G • • WAN Users—These settings determine which packets are covered by the rule, based on their source (WAN) IP address. Select the desired option: – Any — all IP addresses are covered by this rule. – Address range — if this option is selected, you must enter the Start and Finish fields. – Single address — enter the required address in the Start field. Log—You can select whether the traffic will be logged.
Reference Manual for the ADSL Modem Wireless Router DG834G Considerations for Inbound Rules If your external IP address is assigned dynamically by your ISP, the IP address may change periodically as the DHCP lease expires. Consider using the Dynamic DNS feature in the Advanced menu so that external users can always find your network. If the IP address of the local server computer is assigned by DHCP, it may change when the computer is rebooted.
Reference Manual for the ADSL Modem Wireless Router DG834G Outbound Rule Example: Blocking Instant Messenger If you want to block Instant Messenger usage by employees during working hours, you can create an outbound rule to block that application from any internal IP address to any external address according to the schedule that you have created in the Schedule menu. You can also have the modem router log any attempt to use Instant Messenger during that blocked period.
Reference Manual for the ADSL Modem Wireless Router DG834G • • WAN Users—These settings determine which packets are covered by the rule, based on their destination WAN IP address. Select the desired option: – Any — all IP addresses are covered by this rule. – Address range —if this option is selected, you must enter the Start and Finish fields. – Single address — enter the required address in the Start field. Log—You can select whether the traffic will be logged.
Reference Manual for the ADSL Modem Wireless Router DG834G For any traffic attempting to pass through the firewall, the packet information is subjected to the rules in the order shown in the Rules Table, beginning at the top and proceeding to the default rules at the bottom. In some cases, the order of precedence of two or more rules may be important in determining the disposition of a packet. The Move button allows you to relocate a defined rule to a new position in the table.
Reference Manual for the ADSL Modem Wireless Router DG834G • To edit an existing Service, select its button on the left side of the table and click Edit Service. • To delete an existing Service, select its button on the left side of the table and click Delete Service. 3. Use the page shown below to define or edit a service. Figure 5-10 4. Click Apply to save your changes.
Reference Manual for the ADSL Modem Wireless Router DG834G 2. Select the Schedule link of the Security menu to display menu shown below. Figure 5-11 3. Select your time zone.
