Cisco RVS4000 Security Router with VPN Administrator Guide 131
A
using the configuration utility (see Administration > Firmware Upgrade,
page 80). 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 5.0
or Netscape Navigator 5.0 or higher for Macintosh.
I am not able to get the web configuration window for the router. What can I do?
You may have to remove the proxy settings on your web browser. Or remove the
dial-up settings on your browser. Check with your browser documentation. 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 click the Connection
tab. Make sure that Internet Explorer is set to Never dial a connection. For
Netscape Navigator, click Edit > Preferences > Advanced > Proxy. Make sure that
Netscape Navigator is set to Direct connection to the Internet.
What is DMZ Hosting?
Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the
Internet. Some applications require multiple TCP/IP ports to be open. It is
recommended that you set your computer with a static IP if you want to use DMZ
Hosting.
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 2,048 sessions at the same time, but you
can only forward 30 ranges of ports.
