Frequently Asked Questions
Cisco WRVS4400N Wireless-N Gigabit Security Router with VPN Administration Guide
Q. What is the maximum number of IP addresses that the router will support?
The router will support up to 253 IP addresses.
Q. Is IPSec Passthrough supported by the router?
Yes, enable or disable IPSec Passthrough on the VPN > VPN Pass Through
window.
Q. 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.
Q. 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.
Q. 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.
Q. Does the router support any operating system other than Windows 98,
Millennium, 2000, or XP?
Yes, but Cisco does not, at this time, provide technical support for setup,
configuration or troubleshooting of any non-Windows operating systems.
Q. 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.
