Frequently Asked Questions
Can I make calls if my Internet connection is down?
When you make Internet phone calls, your high-speed Internet connection must be active. However, you can
make calls using your landline.
Can I make calls while I’m browsing the Internet?
Yes. You can make calls while browsing the Internet. However, your web browsing may affect the quality of your
Internet calls, depending on the amount of upstream data traffic passing through your Internet connection.
What is the maximum number of IP addresses that the Gateway will support?
The Gateway will support up to 253 IP addresses.
Where is the Gateway installed on the network?
In a typical environment, the Gateway is installed between the cable/DSL modem and the local area network
(LAN). Plug the Gateway into the cable/DSL modem’s Ethernet port.
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 Gateway 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 Gateway support any operating system other than Windows 2000 or XP?
Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of
any non-Windows operating systems.
Is IPSec Passthrough supported by the Gateway?
Yes, it is a built-in feature that is enabled by default.
