FAQs

• Where is the Cable/DSL Router installed on the network?
  
  

  In a typical environment, the Router is installed between the Cable/DSL Modem and the LAN. Plug the Cable/DSL Router into the Cable/DSL Modem's Ethernet port.

• Does the Cable/DSL Router support IPX or AppleTalk?
  
  

  No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications. IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a communications protocol used on Apple and Macintosh networks, can be used from LAN to LAN connections, but those protocols cannot connect from WAN to LAN.

• Does the WAN connection of the Cable/DSL Router support 100Mbps Ethernet?
  
  

  Because of the speed limitations of broadband Internet connections, the Cable/DSL Router's current hardware design supports 10Mb Ethernet on its WAN port. It does, of course, support 100Mbps over in the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the router.

• What is Network Address Translation and what is it used for?
  
  

  Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Cable/DSL Router to be used with low cost Internet accounts, such as DSL or cable modems, where only one TCP/IP address is provided by the ISP. The user may have many private addresses behind this single address provided by the ISP.

• Does the Cable/DSL Router support any operating system other than Windows 95, Windows 98, Windows 2000, or Windows NT?
  
  

  Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of any non-Windows operating systems.

• What is DMZ?
  
  

  Demilitarized Zone (DMZ) allows one IP Address (computer) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open. DMZ allows just one computer to be exposed for that purpose. It is recommended that you set your computer with a static IP if you want to use DMZ.

• If DMZ is used, does the exposed user share the public IP with the Router?
  
  

  No.

• How can I play Internet games (i.e., Ages of Empire) with the router?
  
  

  Enable DMZ in "Advanced Features" of the web configuration screen. For example, if your computer's IP address is 192.168.1.102, enter the last three digits, or "102", in the DMZ field. You may also try using the port forwarding option instead of using DMZ.

• Does the Router pass PPTP packets or actively route PPTP sessions?
  
  

  The Router lets PPTP packets pass through.

• What is the maximum number of users supported by the Router?
  
  

  The Router supports up to 253 users.

• Is the Router cross-platform compatible?
  
  

  Any platform that supports Ethernet & TCP/IP is compatible with the router.

• Will the Router function in a Mac environment?
  
  

  Yes, but Linksys does not provide upgrade programs for Macintoshes. However, you may be able to find some software that uses TFTP for your Macs.

• Will the Router allow you to use your own public IPs and Domain, or do you have to use the IPs provided by the router?
  
  

  The router mode allows for customization of your public IPs and Domain.

• How many ports can be simultaneously forwarded?
  
  

  Theoretically, the Router can establish 520 sessions at the same time, but you can only forward 10 ports.

• Can multiple gamers on the LAN get on one game server and play simultaneously with just one public IP address?
  
  

  It depends on which network game or what kind of game server it is. For example, Unreal Games support multi-login with one public IP.

• Does the Router replace a modem? That is, is there a cable or DSL modem in the router?
  

  No. The Router must work in conjunction with a cable or DSL modem.

• Which modems are compatible with the router?
  
  

  The Router is compatible with any cable or DSL modem that supports Ethernet.

• What are the advanced features of the Router?
  
  

  The Router's advanced features include IP Filtering, IP Forwarding, Dynamic Routing, Static Routing, and DMZ Hosting.

• What is the maximum number of VPN sessions allowed by the router?
  
  

  Only one VPN session at a time.

• How big is the memory buffer on the router?
  
  

  512 Kilobytes.

• How do I access the Router's set-up pages with a Mac?
  
  

  The router's set-up pages are accessible to the Mac through the Mac's web browser, which must be Microsoft Internet Explorer 4.0 or higher, or Netscape Navigator 4.0 or higher. Use the default address 192.168.1.1.

• Can I choose whether to use UDP or TCP on the Router's ports?
  
  

  No, the Router does not have this feature. UDP and TCP are both automatically activated at the same time when the Router's service ports are specified to be opened.

• Does Linksys provide syslog support?
  
  

  At this time, Linksys does not support syslog.

• How can I check whether I have static or DHCP (dynamic) IP addresses?
  
  

  Consult your ISP to confirm this data.

• Does the Router support PPP over Ethernet (PPPoE)?
  
  

  Yes, the router does support PPPoE. The router must have a firmware revision 1.20 or later for PPPoE support. To set up PPPoE support:

  1. Reach the web-based administrative utility by typing "http://192.168.1.1" in your web browser's address line. Press Enter.
  2. A Password window will appear. Type "admin" in the password box and leave the user line blank.
  3. Click Enabled for the PPPoE option and enter the User Name and Password as provided by your Internet Service Provider (ISP). Click Apply, then click Continue.
  4. Click on the Status tab. Scroll down the page. Ensure that PPPoE is Enabled and that its status is selected as Connect.
  
  
• Why does the Router not obtain the IP address assigned by my ISP?
  
  
  1. Make sure that your cable or DSL modem is connected properly.
  2. Try resetting your cable or DSL modem by powering the modem off and on.
  3. If you are using dynamic IP addressing, make sure that your cable or DSL modem is DHCP- capable.
  4. Some ISPs require a MAC address to be registered with them.
  
  
• If all else fails in the installation, what can I do?
  
  
  1. Reset your cable modem or DSL modem by powering the unit off and on.
  2. Obtain the latest release of firmware on the Linksys website, www.linksys.com.
  3. Reset the Router's factory default by holding down the reset button for at least 3 seconds.
  4. Flash the firmware again to the Router, to ensure that it was successfully written to the unit.
  
  
• How will I be notified of new router firmware upgrades?
  
  All Linksys firmware upgrades are posted on the Linksys website at www.linksys.com, where they can be downloaded for free. The router's firmware can be upgraded with TFTP programs.
  
  

  Your Router does NOT need the latest firmware upgrade if your Internet connection is already successful, as firmware upgrades will not increase your connection speed or enhance your Router's performance.

• Does the Router support IPsec?
  
  

  Yes. Firmware Version 1.23.4 and later support IPsec. IPsec is a security protocol that provides authentication and encryption over the Internet. Unlike SSL, which provides services at layer 4 and secures two applications, IPSEC works at layer 3 and secures everything in the network.

• What type of firewall is the router equipped with?
  
  

  The Router uses NAT and TCP/IP port inspections.

• Does the Router do Stateful packet inspection?
  
  

  No.

• I am not able to get my e-mails or my ISP web page (e.g., http://www.isp.com/). What can I do?
  
  

  Contact the ISP to get the full URL, or you can do the following:

  1. Connect one of the computers directly to the cable modem or DSL modem.
  2. Open a command prompt and ping the ISP web server or mail server name given. For example, at the command prompt, type in ping www and press Enter. You should be able to get an IP address when it responds.
  3. After you get the IP address, enter the IP address on the mail server option.
  
  
• I am not able to get the web configuration screen for the router. What can I do?
  
  You may have to remove proxy settings on your Internet browser, e.g., Netscape or Internet Explorer. Or, remove the dial-up settings on your browser.
