Wireless-G VPN Router with RangeBooster

Appendix A

in one network cannot see the computers in the remote

network from Windows Explorer.

The WRV200 does not support NetBIOS Broadcast over

a Gateway-to-Gateway IPSec VPN tunnel. To access the

computers or shared drives on the remote network, users

are advised to use the IP address to identify the resource.

Frequently Asked Questions

What is the maximum number of IP addresses that the

Router will support?

The Router will support up to 253 IP addresses.

Is IPSec Passthrough supported by the Router?

Yes, you can enable or disable IPSec Passthrough on the

VPN > VPN Passthrough

screen.

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 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 for LAN to LAN connections, but

those protocols cannot connect from the Internet to the

LAN.

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 2000 or Windows XP?

Yes, but Linksys does not, at this time, provide technical

support for setup, configuration or troubleshooting 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 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. 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 to 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.

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 computer.

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
