D. In the command prompt, type ping followed by your WAN or Internet IP address and press the Enter key.
Instant Wireless® Series Your VPN may require port 500/UDP packets to be passed to the computer that is connecting to the IPSec server. Refer to “Problem #7, I need to set up online game hosting or use other Internet applications” for details. Check the Linksys website for more information at www.linksys.com. 6. I need to set up a server behind my Router. To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using.
Instant Wireless® Series 8. I can’t get the Internet game, server, or application to work. If you are having difficulties getting any Internet game, server, or application to function properly, consider exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an application requires too many ports or when you are not sure which port services to use.
Instant Wireless® Series 13. The firmware upgrade failed, and/or the Diag LED is flashing. The upgrade could have failed for a number of reasons. Follow these steps to upgrade the firmware and/or make the Diag LED stop flashing: A. If the firmware upgrade failed, use the TFTP program (it was downloaded along with the firmware). Open the pdf that was downloaded along with the firmware and TFTP program, and follow the pdf’s instructions. B.
Instant Wireless® Series 17. The Diag LED stays lit continuously. • The Diag LED lights up when the device is first powered up. Meantime, the system will boot up itself and check for proper operation. After finishing the checking procedure, the LED turns off to show that the system is working fine. If the LED remains lit after this time, the device is not working properly. Try to flash the firmware by assigning a static IP address to the computer, and then upgrade the firmware.
Instant Wireless® Series Does the Router support ICQ send file? Yes, with the following fix: click ICQ menu -> preference -> connections tab->, and check I am behind a firewall or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file to a user behind the Router. I set up an Unreal Tournament Server, but others on the LAN cannot join.
Instant Wireless® Series Is the Router cross-platform compatible? Any platform that supports Ethernet and TCP/IP is compatible with the Router. How many ports can be simultaneously forwarded? Theoretically, the Router can establish 520 sessions at the same time, but you can only forward 10 ranges of ports. Does the Router replace a modem? Is there a cable or DSL modem in the Router? No, this version of the Router must work in conjunction with a cable or DSL modem.
Instant Wireless® Series without the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers. Would the information be intercepted while transmitting on air? WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence Spread Spectrum technology, it has the inherent security feature of scrambling.
Instant Wireless® Series 3. At the DOS command prompt, type “ping mail” (assuming that the location for which you’re trying to find an IP address is configured as “mail”). Press Enter. Information such as the following data, taken from a ping of Microsoft Network’s e-mail server, will be displayed.
