Wireless-G VPN Broadband Router Chapter 1: Introduction Welcome Thank you for choosing the Linksys Wireless-G VPN Broadband Router. The Wireless-G VPN Broadband Router will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely. How does the Wireless-G VPN Broadband Router do all of this? A router is a device that allows access to an Internet connection over a network.
Wireless-G VPN Broadband Router You should always use the Setup CD-ROM when you first install the Router. If you do not wish to run the Setup Wizard on the Setup CD-ROM, then use the instructions in this Guide to help you connect the Wireless-G VPN Broadband Router, set it up, and configure it to bridge your different networks. These instructions should be all you need to get the most out of the Wireless-G VPN Broadband Router.
Wireless-G VPN Broadband Router • Appendix D: Configuring IPSec between a Windows 2000 or XP PC and the Router This appendix instructs you on how to establish a secure IPSec tunnel using preshared keys to join a private network inside the VPN Router and a Windows 2000 or XP PC. • Appendix E: Configuring VPN Tunnels This appendix describes how to configure VPN IPSec tunnels using the VPN Routers and a VPN client. • Appendix F: Finding the MAC Address and IP Address for your Ethernet Adapter.
Wireless-G VPN Broadband Router Chapter 2: Planning Your Wireless Network Network Topology A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the same wireless network.
Wireless-G VPN Broadband Router The Wireless-G VPN Broadband Router is compatible with all 802.11b and 802.11g adapters, such as the Notebook Adapters (WPC54G, WPC11) for your laptop computers, PCI Adapter (WMP54G, WMP11) for your desktop PC, and USB Adapter (WUSB54G, WUSB11) when you want to enjoy USB connectivity. The Broadband Router will also communicate with the Wireless PrintServer (WPS54GU2, WPS11) and Wireless Ethernet Bridges (WET54G, WET11).
Wireless-G VPN Broadband Router Chapter 3: Planning Your Virtual Private Network (VPN) Why do I need a VPN? Computer networking provides a flexibility not available when using an archaic, paper-based system. With this flexibility, however, comes an increased risk in security. This is why firewalls were first introduced. Firewalls help to protect data inside of a local network.
Wireless-G VPN Broadband Router data to a new destination. Even though the data is not received by its intended recipient, it appears that way to the person sending the data. These are only a few of the methods hackers use and they are always developing more. Without the security of your VPN, your data is constantly open to such attacks as it travels over the Internet. Data travelling over the Internet will often pass through many different servers around the world before reaching its final destination.
Wireless-G VPN Broadband Router and the Router”). Other versions of Microsoft operating systems require additional, third-party VPN client software applications that support IPSec to be installed. VPN Router to VPN Router An example of a VPN Router-to-VPN Router VPN would be as follows. At home, a telecommuter uses his VPN Router for his always-on Internet connection. His router is configured with his office's VPN settings.

Wait 30 seconds, and then turn on the Router, cable/DSL modem, and computer. Check the Status tab of the Router’s web-based utility to see if you get an IP address. 5.
Wireless-G VPN Broadband Router 7. I need to set up a server behind my Router and make it available to the public. To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using. For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the documentation provided with the server you installed.
Wireless-G VPN Broadband Router 2. Enter any name you want to use for the Customized Application. 3. Enter the External Port range of the service you are using. For example, if you want to host Unreal Tournament (UT), you would enter the range 7777 to 27900. 4. Check the protocol you will be using, TCP and/or UDP. 5. Enter the IP address of the PC or network device that you want the port server to go to. For example, if the web server’s Ethernet adapter IP address is 192.168.1.
Wireless-G VPN Broadband Router 10. I forgot my password, or the password prompt always appears when I am saving settings to the Router. • Reset the Router to factory default by pressing the Reset button for 10 seconds and then releasing it.

Wireless-G VPN Broadband Router How do I get Half-Life: Team Fortress to work with the Router? The default client port for Half-Life is 27005. The computers on your LAN need to have “+clientport 2700x” added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect to the same server. One problem: Version 1.0.1.6 won’t let multiple computers with the same CD key connect at the same time, even if on the same LAN (not a problem with 1.0.1.3).
Wireless-G VPN Broadband Router then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy.

Some applications require multiple TCP/IP ports to be open.
Wireless-G VPN Broadband Router Can I run an application from a remote computer over the wireless network? This will depend on whether or not the application is designed to be used over a network. Consult the application’s documentation to determine if it supports operation over a network. What is the IEEE 802.11b standard? It is one of the IEEE standards for wireless networks. The 802.
Wireless-G VPN Broadband Router What is infrastructure mode? When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a wired network through a wireless access point. What is roaming? Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single access point.
Wireless-G VPN Broadband Router What is DSSS? What is FHSS? And what are their differences? Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence SpreadSpectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted.
Wireless-G VPN Broadband Router How many channels/frequencies are available with the Router? There are eleven available channels, ranging from 1 to 11 (in North America). If your questions are not addressed here, refer to the Linksys website, www.linksys.com.
