manual abstract
The subnet mask that is assigned to the router. Default Gateway. The IP address for the default gateway that the router communicates with. DHCP Server. The IP address for the Dynamic Host Configuration Protocol server that provides the TCP/IP configuration for all the computers that are connected to the router. DNS Server. The IP address of the Domain Name Service server that provides translation of network names to IP addresses. Lease Obtained. The date and time that the lease was obtained. Lease Expires. The date and time that the lease expires. View Attached Devices The Attached Devices screen presents a table of all IP devices that the router has discovered on the local network. Select Maintenance > Attached Devices to view the following table: For each device, the table shows the IP address, device name if available, and the Ethernet MAC address. Note that if the router is rebooted, the table data is lost until the router rediscovers the devices. To force the router to look for attached devices, click the Refresh button. Remote Management Access Using the Remote Management feature, you can allow a user on the Internet to configure, upgrade, and check the status of your JWNR2000v2 router. To set up your router for remote management: 1. Select Advanced > Remote Management. The Remote Management screen displays. 2. Make sure that you have changed the router’s default password to a very secure password. The ideal password should contain no dictionary words from any language, and should be a mixture of letters (both uppercase and lowercase), numbers, and symbols. Your password can be up to 30 characters. 3. Select the Turn Remote Management On check box. 4. Under Allow Remote Access By, specify what external IP addresses will be allowed to access the router’s remote management. For enhanced security, restrict access to as few external IP addresses as practical. • To allow access from any IP address on the Internet, select Everyone. • To allow access from a range of IP addresses on the Internet, select IP Address Range. Enter a beginning and ending IP address to define the allowed range. • To allow access from a single IP address on the Internet, select Only This Computer. Enter the IP address that will be allowed access. 5. Specify the port number for accessing the management interface. Normal Web browser access uses the standard HTTP service port 80. For greater security, enter a custom port number for the remote management Web interface. Choose a number between 1024 and 65535, but do not use the number of any common service port. The default is 8080, which is a common alternate for HTTP. 6. Click Apply to have your changes take effect. When accessing your router from the Internet, enter your router’s WAN IP address into your browser’s address or location field, followed by a colon (:) and the custom port number. For example, if your external address is 134.177.0.123 and you use port number 8080, then enter in your browser. 6. Advanced Settings Configuring for unique situations This chapter describes the advanced features of your router. The information is for users with a solid understanding of networking concepts who want to set the router up for unique situations such as when remote access from the Internet by IP or domain name is needed. It contains the following sections: • WAN Setup • Dynamic DNS • LAN Setup • Advanced Wireless Settings • Set Up Static Routes • Quality of Service • Universal Plug and Play • Wireless Repeating (Also Called WDS) For information about port triggering and port forwarding, see Chapter 4, Content Filtering. WAN Setup The WAN Setup screen lets you disable port scan and DoS protection, configure a DMZ (demilitarized zone) server, enable the router to respond to a ping on the WAN (Internet) port, enable IGMP proxying, and change the Maximum Transmit Unit (MTU) size. Select Advanced > WAN Setup to display the following screen: Disable Port Scan and DOS Protection. The firewall protects your LAN against port scans and denial of service (DOS) attacks. This protection should be disabled only in special circumstances. Default DMZ Server. The default demilitarized zone (DMZ) server feature is helpful when you use online games and video conferencing applications that are incompatible with NAT. The router is programmed to recognize some of these applications and to work correctly with them, but there are other applications that might not function well. In some cases, one local computer can run the application correctly if that computer’s IP address is entered as the default DMZ server. Respond to Ping on Internet. If you want the router to respond to a ping from the Internet, select this check box. This should be used only as a diagnostic tool, because it allows your router to be discovered. Do not select this check box unless you have a specific reason to do so. Disable IGMP Proxying. IGPM (Internet Group Management Protocol) proxying is disabled by default...
