10. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-
up window.
If you have proxy settings, you need to disable these on your computer.
Because the Router is the gateway for the Internet connection, the computer
does not need any proxy settings to gain access.
Please follow these directions
to verify that you do not have any proxy settings and that the browser you use
is set to connect directly to the LAN.
For Microsoft Internet Explorer 5.0 or higher
:
A. Click
Start
,
Settings
, and
Control Panel
. Double-click
Internet Options
.
B.
Click the
Connections
tab.
C.
Click the
LAN settings
button and remove anything that is checked.
D.
Click the
OK
button to go back to the previous screen.
E.
Click the option
Never dial a connection
.
This will remove any dial-up
pop-ups for PPPoE users.
For Netscape 4.7 or higher
:
A. Start
Netscape Navigator
, and click
Edit
,
Preferences
,
Advanced
, and
Proxies
.
B.
Make sure you have
Direct connection to the Internet
selected on this
screen.
C.
Close all the windows to finish.
11. How do I set the Router to factory default?

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 applica-
tion requires too many ports or when you are not sure which port services to
use. Make sure you disable all the forwarding entries if you want to success-
fully use DMZ hosting, since forwarding has priority over DMZ hosting. (In
other words, data that enters the Router will be checked first by the forwarding
settings. If the port number that the data enters from does not have port for-
warding, then the Router will send the data to whichever PC or network device
you set for DMZ hosting.)
Follow these steps to set DMZ hosting:
A. Open the Router’s Web-based Utility, as shown in “Chapter 6: The
Cable/DSL VPN Router’s Web-based Utility” and go to the
Advanced =>
Filter
tab.
B.
Disable or remove the entries you have entered for forwarding.
Keep this
information in case you want to use it at a later time.
C.
Click the
DMZ Host
tab.
D.
Enter the Ethernet adapter’s
IP address
of the computer you want exposed
to the Internet.
This will bypass the NAT firewall for that computer. Please
refer to “Appendix G: Finding the MAC Address and IP Address for Your
Ethernet Adapter” for details on getting an IP address.
Once completed with the configuration, click the
Apply
button and then the
Continue
button.
9.
I forgot my password, or the password prompt always appears when saving
settings to the Router.
Reset the Router to factory default by pressing the
Reset
button for 30 seconds
and then releasing it. If you are still getting prompted for a password when sav-
ing settings, then perform the following steps:
A. Open the Router’s Web-based Utility, as shown in “Chapter 6: The
Cable/DSL VPN Router’s Web-based Utility”. Enter the default password
admin
, and click the
Password
tab.
B.
Enter a
different password
in the Web-based Utility’s Password field, and
enter the same password in the second field to confirm the password.
C.
Click the
Apply
and
Continue
buttons.

Frequently Asked Questions
What is MIB?
MIB (Management Information Base) is a data file that works in
tangent with third-party SNMP software in managing the Router. To use MIB
files in tangent with third-party SNMP software, follow the instructions that
come with the thirty-party SNMP software. MIB data files will be available
on the Linksys web site: www.linksys.com.
Can I use firmware for other routers with the BEFVP41?
No. If you attempt to use
other router's firmware, you could damage the Router. Only use firmware
specifically written for the BEFVP41 as posted on the Linksys web site:
www.linksys.com
.
What is SNMP?
SNMP (
S
imple
N
etwork
M
anagement
P
rotocol) is a widely-
used network monitoring and control protocol. For more information on
SNMP, see “Appendix D: SNMP Functions.”
What is the maximum number of IP addresses that the Router will support?
The
Router will support up to 253 IP addresses.
Does the Router support IPSec Pass-Through?
Yes, it is a built-in feature that the
Router automatically enables.
Where is the Router installed on the network?
In a typical environment, the
Router is installed between the cable/DSL modem and the LAN.
Plug the
Router into the cable/DSL modem’s Ethernet port.
Does the Router support IPX or AppleTalk?
No. TCP/IP is the only protocol stan-
dard 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 for LAN to LAN connections,
but those protocols cannot connect from WAN to LAN.
Does the Router’s WAN connection support 100 Mbps Ethernet?
Because of the
speed limitations of broadband Internet connections, the Router’s WAN port
supports 10 Mbps Ethernet. It does, of course, support 100 Mbps over its
auto-sensing 10/100 ports.
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. Try using the following settings, IP Address:
192.168.1.50 and Subnet Mask: 255.255.255.0.
18. When I enter a URL or IP address, I get a time-out error or am prompted to retry.
A.
Check if other PCs work. If they do, ensure that your workstation’s IP set-
tings are correct (IP Address, Subnet Mask, Default Gateway, and DNS).
Restart the computer that is having a problem.
B.
If the PCs are configured correctly, but still not working, check the
Router.
Verify that it is connected and ON. (If you cannot connect to it, check the
LAN and power connections.)
C. If the Router is configured correctly, check your Internet connection
(DSL/cable modem, etc.) to see if it is working correctly. You can remove
the Router to verify a direct connection.
D.
Manually configure the TCP/IP with a DNS address provided by your ISP.
E.
Make sure that your browser is set to connect directly and that any dial-up
is disabled. For Internet Explorer, click
Tools
,
Internet Options
, and 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
. Make sure that Netscape Navigator is set to
Direct connection
to the Internet
.
19. The Full/Col LED keeps flickering continuously.
A.
Check the Category 5 Ethernet cable and its RJ-45 connectors.
B.
There may be interference with other network devices. Try removing other
PCs or network devices to see if the problem persists. Eliminate each net-
work device one at a time to determine the cause.

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).
As far as hosting games, the HL server does not need to be in the
DMZ. Just forward port 27015 to the local IP address of the server comput-
er.
How can I block corrupted FTP downloads?
If you are experiencing corrupted
files when you download a file with your FTP client, try using another FTP
program.
The web page hangs; downloads are corrupt, or nothing but junk characters are
being displayed on the screen. What do I need to do?
Force your Ethernet
adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate”
feature of your Ethernet adapter as a temporary measure. (Please look at the
Network Control Panel in your Ethernet adapter’s Advanced Properties tab.)
Make sure that your proxy setting is disabled in the browser. Check our web-
site at
www.linksys.com
for more information.
If all else fails in the installation, what can I do?
Reset the Router by holding
down the reset button until the Diag LED fully turns on and off. Reset your
cable or DSL modem by powering the unit off and then on.
Obtain and flash
the latest firmware release that is readily available on the Linksys website,
www.linksys.com
.
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. If the Router’s Internet connection is working well, there is
no need to download a newer firmware version, unless that version contains
new features that you would like to use.
Downloading a more current version
of Router firmware will not enhance the quality or speed of your Internet
connection, and may disrupt your current connection stability.
Will the Router function in a Macintosh environment?
Yes, but the Router’s setup
pages are accessible only through Internet Explorer 4.0 or Netscape
Navigator 4.0 or higher for Macintosh.

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 Router to be used with low cost
Internet accounts, such as DSL or cable modems, when 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 Router support any operating system other than Windows 95, Windows
98, Windows 2000, Windows NT, or Windows XP?
Yes, but Linksys does not, at
this time, provide technical support for setup, configuration or troubleshoot-
ing of any non-Windows operating systems.
Does the Router support ICQ send file?
Yes, with the following fix: click
ICQ
menu -> preference -> connections tab->
, and check
I am behind a fire-
wall or proxy
. Then set the firewall time-out to
80
seconds in the firewall set-
ting. 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. What do
I need to do?
If you have a dedicated Unreal Tournament server running, you
need to create a static IP for each of the LAN computers and forward ports
7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You
can also use a port forwarding range of 7777 ~ 27900. If you want to use the
UT Server Admin, forward another port (8080 usually works well but is used
for remote admin. You may have to disable this.), and then in the
[UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to
match the mapped port above) and ServerName to the IP assigned to the
Router from your ISP.
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 you are using.
For example, Unreal Tournament supports
multi-login with one public IP.

What is the maximum number of VPN sessions allowed by the Router?
The maximum number depends on many factors. At least one IPSec session
will work through the Router; however, simultaneous IPSec sessions
may
be
possible, depending on the specifics of your VPNs.
How big is the Router’s memory buffer?
It includes a 1MB buffer and 512KB
flash.
How can I check whether I have static or DHCP IP Addresses?
Consult your ISP
to obtain this information.
How do I get mIRC to work with the Router?
Under the Port Range Forwarding
tab, set port forwarding to 113 for the PC on which you are using mIRC.
If your questions are not addressed here, refer to the Linksys website,

What is DMZ Hosting?
Demilitarized Zone (DMZ) allows one IP address (com-
puter) to be exposed to the Internet.
Some applications require multiple
TCP/IP ports to be open.
You should set your computer with a static IP if you
want to use DMZ Hosting. To get the LAN IP address, see “Appendix G:
Finding the MAC Address and IP Address for Your Ethernet Adapter.”
If DMZ Hosting is used, does the exposed user share the public IP with the Router?
No.
Does the Router pass PPTP packets or actively route PPTP sessions?
The Router
allows PPTP packets to pass through.
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.
Which modems are compatible with the Router?
The Router is compatible with
virtually any cable or DSL modem that supports Ethernet.
What are the Router’s advanced features?
The Router’s advanced features
include IP Filtering, Port Range Forwarding, Dynamic Routing, Static
Routing, DMZ hosting, and MAC Address Cloning.
