[. . . ] Note: For enhanced security, restrict access to as few external IP addresses as practical. a. To allow access from any IP address on the Internet, select Everyone. 7-16 Advanced Configuration of the Router July 2004 202-10036-01 Reference Manual for the 54 Mbps Wireless Router WGR614 v5 b. 3. To allow access from a range of IP addresses on the Internet, select IP address 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. Specify the Port Number that will be used for accessing the management interface. For greater security, change the remote management Web interface to a custom port by entering that number in the box provided. 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. 4. Click Apply to have your changes take effect. Note: When accessing your router from the Internet, you will type your router's WAN IP address into your browser's Address (in IE) or Location (in Netscape) box, 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, you must enter http://134. 177. 0. 123:8080 in your browser. Using Universal Plug and Play (UPnP) Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network. Figure 7-9. UPnP Menu 7-17 Advanced Configuration of the Router July 2004 202-10036-01 Reference Manual for the 54 Mbps Wireless Router WGR614 v5 From the Main Menu of the browser interface, under Advanced, click on UPnP. Turn UPnP On: UPnP can be enabled or disabled for automatic device configuration. If disabled, the router will not allow any device to automatically control the resources, such as port forwarding (mapping), of the router. Note: If you use applications such as multi-player gaming, peer-to-peer connections, real time communications such as instant messaging, or remote assistance (a feature in Windows XP), you should enable UPnP. Advertisement Period: The Advertisement Period is how often the router will broadcast its UPnP information. Shorter durations will ensure that control points have current device status at the expense of additional network traffic. Longer durations may compromise the freshness of the device status but can significantly reduce network traffic. Advertisement Time To Live: The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is allowed to propagate for each UPnP advertisement before it disappears. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, then it may be necessary to increase this value a little. UPnP Portmap Table: The UPnP Portmap Table displays the IP address of each UPnP device that is currently accessing the router and which ports (Internal and External) that device has opened. The UPnP Portmap Table also displays what type of port is opened and if that port is still active for each IP address. 7-18 Advanced Configuration of the Router July 2004 202-10036-01 Chapter 8 Troubleshooting This chapter gives information about troubleshooting your 54 Mbps Wireless Router WGR614 v5. After each problem description, instructions are provided to help you diagnose and solve the problem. Basic Functioning After you turn on power to the router, the following sequence of events should occur: 1. [. . . ] The subnet mask is the network address plus the bits reserved for identifying the subnetwork. (By convention, the bits for the network address are all set to 1, though it would also work if the bits were set exactly as in the network address. ) In this case, therefore, the subnet mask would be 11111111. 11111111. 11110000. 00000000. It's called a mask because it can be used to identify the subnet to which an IP address belongs by performing a bitwise AND operation on the mask and the IP address. The result is the subnetwork address: Subnet Mask 255. 255. 240. 000 11111111. 11111111. 11110000. 00000000 IP Address 150. 215. 017. 009 10010110. 11010111. 00010001. 00001001 Subnet Address 150. 215. 016. 000 10010110. 11010111. 00010000. 00000000 The subnet address, therefore, is 150. 215. 016. 000.
