10.2 Frequently Asked Questions
What is the purpose of Network Address Translation?
NAT handles the conversion of the Public WAN IP to 253 Private LAN IPs as well
as showing only the Public IP on the Internet, keeping the Private IP hidden. This
helps ensure security since each outgoing or incoming request must go through a
translation process that also offers the opportunity to qualify or authenticate the
request or match it to a previous request. NAT also acts as the firewall in the
XRouter, thus allowing for a layer of security between you and the Internet.
I have a CAT-5 Ethernet cable connected but it won’t give me a LNK LED
light.
Cabling is where a majority of network problems occur. Check that the cable gives
the proper LED lights. If not, try a second cable. Be sure you’re using the correct
cable, either a Standard Ethernet cable or a Crossover cable. Most likely you’ll
need a CAT-5 Standard Ethernet cable, such as when connecting a computer to
our XRouter, but this is not always the case.
Where do I obtain the MAC Address from my NIC for filtering purposes?
This information is located on the Properties tab of your NIC card. See your
Windows OS Manual.
What VPN support does the XROUTER AERO unit offer?
Only PPTP and IPSec Nortel Extranet Null Standard are supported.
What ISPs or DSL/Cable modems are compatible with the XRouter Aero?
If the ISP or DSL/Cable modem use standard TCP/IP and Ethernet then they are
compatible with the XRouter.
What is a DNS Server and why do I need DNS numbers?
Domain Names (i.e.: www.yahoo.com) were created because it would be too
difficult for us to remember the IP Address for every website. It’s easier to
remember Yahoo.com instead of 204.71.200.68. Before connecting the user to
the website, a DNS server will do the translation to the IP and then serve up the
request, such as a web page. This accounts for the different lag times when
requesting sites on the Net.
I don’t know the specific virtual ports for my software. Where do I get them?
The user must obtain the correct ports from the software manufacturer to allow
the service through the firewall. Check their manual, website or call their technical
support.
Does the XRouter Aero support QuickTime Streaming?
Yes. QuickTime 5 and older versions have been tested extensively through the
XRouter Aero.
I’m having trouble with the installation process, what are my options at this
point?
The installation process is meant to be simple as long as the instructions are
followed properly. Xsense suggests initially installing and configuring the XRouter
with only one computer. Ensure the cable connection shows the proper LNK LED
light indication. Double-check your TCP/IP settings and if uncertain, give your
