Help: To request help information. 3.5.6 Protocol-based NAT This wireless router supports NAT by IP protocol. Users can specify an IP protocol number and internal host’s IP address to let the gateway masquerade IP header then forward to that internal host. This could be useful if user wants to setup a protocol proxy inside LAN.
- - - - - Default don’t masquerade source port number for new UDP flows: The wireless router will try to keep LAN to WAN source UDP port number when doing NAPT if possible. Doing so helps some NAT unfriendly application without ALG module pass NAT gateway. Default don’t masquerade source port number for new TCP flows: The wireless router will try to keep LAN to WAN source TCP port number when doing NAPT if possible. Doing so helps some NAT unfriendly application without ALG module pass NAT gateway.

Appendix A: Troubleshooting Symptom Inability to access the router Possible Causes Things to Do • Verify that the wireless • Incorrect or incompatible wireless network configuration. network configurations between the wireless client For example, shared key authentication is configured on and wireless AP/Router are the wireless AP/Router and the compatible. Make sure that the client system’s network card is wireless client is attempting set to receive IP automatically.
Intermittent connectivity • AP/Router is not power on • Check the “Power” LED. Make sure that you've plugged in the power cord. • IEEE 802.1X authentication is enabled on the wireless client and is not enabled on the wireless AP/Router • The symptom of this issue is when the wireless client loses connectivity every 3 minutes or so. Disable the authentication feature on the wireless client.
• On a laptop computer, the Configuration services are wireless radio button might be configured to start in the off position automatically. • A wireless network adapter driver failing in early stages of service startup may result in the Wireless Zero Configuration or Wireless Configuration service not initializing over that interface. Client can't connect to the AP/Router's configuration utility. • Wrong IP address 56 • Make sure that your PC is using an IP address within the correct range.
Appendix B: Frequently Asked Questions Q1: What is wireless networking? Ans: The term wireless networking refers to the technology that enables two or more computers to communicate using standard network protocols, but without network cabling. Strictly speaking, any technology that does this could be called wireless networking. The current buzzword however generally refers to wireless LANs. This technology, fuelled by the emergence of cross-vendor industry standards such as IEEE 802.
Figure A2: Hardware Access Point. Wireless connected computers using a Hardware Access Point. Figure A3: Software Access Point. Wireless connected computers using a Software Access Point. Q3: Can I mix wireless equipment from different vendors? Ans: Because most wireless networking hardware vendors support the 802.11 standard they can inter operate.
also allow considerable flexibility in providing access to different network types, such as different types of Ethernet, Wireless and Token Ring networks. Such connections are only limited by the number of slots or interfaces in the computer used for this task. Further to this the software access point may include significant additional features such as shared Internet access, web caching or content filtering, providing significant benefits to users and administrators.
is analogous to Ethernet cabling, the answer to this question becomes clear. To share an Internet connection across a LAN you need two things: (1) an Internet sharing hardware device or software program (2) connection to a LAN If your LAN is wireless, the same criteria apply. You need hardware or software access point and a wireless LAN. Any computer equipped with a wireless network card running suitable Internet sharing software can be used as a software access point.
produces secure scrambled text. Decryption is the opposite of encryption; it is the mathematical operation that transforms cipher text to standard text. Q11: Why do I need a router? Ans: The increased reliance on computers to store valuable information and the development of applications that share information over the internet through networked personal computers, in combination with the advent of computer hacking, has made information and network security an important issue.
Q21: What is the maximum number of users the Access Point facilitates? Ans: It depends on the volume of data and may be less if many users create a large amount of network traffic. Q22: What is the maximum number of IP addresses that the Router will support? Ans: The Router will support up to 253 IP addresses. Q23: Where is the Router installed on the network? Ans: In a typical environment, the Router is installed between the cable/DSL modem and the LAN.
