Chapter 5 Fine-Tuning Your Network This chapter describes how to modify the configuration of the Wireless-G Router Model WGR614v9 to allow specific applications to access the Internet or to be accessed from the Internet, and how to make adjustments to enhance your network’s performance.
Wireless-G Router WGR614v9 Reference Manual How Your Computer Accesses a Remote Computer through Your Router When a computer on your network needs to access a computer on the Internet, your computer sends your router a message containing source and destination address and process information. Before forwarding your message to the remote computer, your router must modify the source information and must create and track the communication session so that replies can be routed back to your computer.
Wireless-G Router WGR614v9 Reference Manual 4. The Web server at www.example.com composes a return message with the requested Web page data. The return message contains the following address and port information: • The source address is the IP address of www.example.com. • The source port number is 80, the standard port number for a Web server process. • The destination address is the public IP address of your router. • The destination port number is 33333.
Wireless-G Router WGR614v9 Reference Manual “When you initiate a session with destination port 6667, you must also allow incoming traffic on port 113 to reach the originating computer.” Using steps similar to the preceding example, the following sequence shows the effects of the port triggering rule you have defined: 1. You open an IRC client program, beginning a chat session on your computer. 2.
Wireless-G Router WGR614v9 Reference Manual How Port Forwarding Changes the Communication Process In both of the preceding examples, your computer initiates an application session with a server computer on the Internet. However, you might need to allow a client computer on the Internet to initiate a connection to a server computer on your network. Normally, your router ignores any inbound traffic that is not a response to your own outbound traffic.
Wireless-G Router WGR614v9 Reference Manual How Port Forwarding Differs from Port Triggering The following points summarize the differences between port forwarding and port triggering: • Port triggering can be used by any computer on your network, although only one computer can use it at a time. • Port forwarding is configured for a single computer on your network. • Port triggering does not need to know the computer’s IP address in advance. The IP address is captured automatically.
Wireless-G Router WGR614v9 Reference Manual To configure port forwarding to a local server: 1. Select Port Forwarding/Port Triggering under Advanced in the main menu. Figure 5-1 2. From the Service Name list, select the service or game that you will host on your network. If the service does not appear in the list, see the following section, “Adding a Custom Service.” 3.
Wireless-G Router WGR614v9 Reference Manual 2. Click Add Custom Service. Figure 5-2 3. In the Service Name field, enter a descriptive name. 4. In the Service Type field, select the protocol. If you are unsure, select TCP/UDP. 5. In the Starting Port field, enter the beginning port number. • If the application uses only a single port, enter the same port number in the Ending Port field. • If the application uses a range of ports, enter the ending port number of the range in the Ending Port field. 6.
Wireless-G Router WGR614v9 Reference Manual To make a local Web server public: 1. Assign your Web server either a fixed IP address or a dynamic IP address using DHCP address reservation, as explained in “Using Address Reservation” on page 4-3. In this example, your router will always give your Web server an IP address of 192.168.1.33. 2. In the Port Forwarding screen, configure the router to forward the HTTP service to the local address of your Web server at 192.168.1.33.
Wireless-G Router WGR614v9 Reference Manual To configure port triggering, you need to know which inbound ports the application needs. Also, you need to know the number of the outbound port that will trigger the opening of the inbound ports. You can usually determine this information by contacting the publisher of the application or user groups or newsgroups. To set up port triggering: 1. Select Port Forwarding/Port Triggering under Advanced in the main menu. The Forwarding/Port Triggering screen displays.
Wireless-G Router WGR614v9 Reference Manual 4. In the Port Triggering Timeout field, enter a value up to 9999 minutes. This value controls the inactivity timer for the designated inbound ports. The inbound ports close when the inactivity time expires. This is required because the router cannot be sure when the application has terminated. 5. Click Add Service. Figure 5-4 6. In the Service Name field, type a descriptive service name. 7.
Wireless-G Router WGR614v9 Reference Manual Using Universal Plug and Play Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, to 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.
Wireless-G Router WGR614v9 Reference Manual • Advertisement Period. The advertisement period is how often the router broadcasts its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that control points have current device status at the expense of additional network traffic. Longer durations might compromise the freshness of the device status but can significantly reduce network traffic. • Advertisement Time To Live.
Wireless-G Router WGR614v9 Reference Manual • • • • Choose placement carefully. For best results, place your router: – Near the center of the area in which your computers will operate. – In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls). – Avoid obstacles to wireless signals.
Wireless-G Router WGR614v9 Reference Manual Changing the MTU Size The Maximum Transmission Unit (MTU) is the largest data packet a network device transmits. When one network device communicates across the Internet with another, the data packets travel through many devices along the way. If any device in the data path has a lower MTU setting than the other devices, the data packets must be split or “fragmented” to accommodate the one with the smallest MTU.
Wireless-G Router WGR614v9 Reference Manual If you suspect an MTU problem, a common solution is to change the MTU size to 1400. If you are willing to experiment, you can gradually reduce the MTU size from the maximum value of 1500 until the problem goes away. Table 5-1 describes common MTU sizes and applications. Table 5-1. Common MTU Sizes MTU Application 1500 The largest Ethernet packet size and the default value.
Wireless-G Router WGR614v9 Reference Manual • Wireless. Your Wireless-G Router Model WGR614v9 provides a wireless data throughput of up to 300 Mbps using technology called multiple input, multiple output (MIMO), in which multiple antennas transmit multiple streams of data. The use of multiple antennas also provides excellent range and coverage. With the introduction of the newer WPA and WPA2 encryption and authentication protocols, wireless security is extremely strong.
Wireless-G Router WGR614v9 Reference Manual • Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so a congested network or a noisy link can cause problems. • Backing up computers over the network has become popular due to the availability of inexpensive mass storage. Table 5-2 shows the time to transfer 1 gigabyte (1 GB) of data using various networking technologies.
