Multiple IP Addresses on Single NIC

[Mark King MCP]

Hi,

Please can someone email me the answer to this query? My
father has Win XP Pro with a single on-board NIC. I need
to give him 2 static IP addresses (one internal & one for
the the broadband). I have setup a W2K domain which he
can join easily enough. The problems arise when I try to
ping the DC (my computer). With both IP's configured, the
ping ends up pointing to my hosting provider. When I have
only the internal details setup, the ping points to where
it should.

If you would like to call me, then please drop me an email
and I will supply my phone number.

Having 2 different subnets on one NIC is generally not the best approach.
Where does the cable from your father's NIC go, and what is your Win2K
domain connected to?
If this is a home network situation, you want whatever is connected to the
actual Internet connection to have the broadband IP address, and use that
device to share the connection to everything else.

Alternatively, you can add another NIC to the machine, and connect one NIC
directly to the DC, and connect the other to the broadband connection.

Hi,

The broadband is plugged directly into a hub, which is
where both me and my father plug into. He is using a
laptop whilst I have the desktop. We don't really want
the expense of having to buy another NIC just so that we
can share printer. The reason for the domain is that I am
currently study for my MCSE in W2K.

Hi Mark,

Doing it this way is actually not recommended, and can be a major security
risk. What happens is that both computers are directly connected to the
Internet with no firewall, and anyone on the Internet may have the
opportunity to try to access anything on your network.
The best way to properly set this up is to use either a hardware firewall
(like a Linksys, Netgear, D-Link, etc, router), which means the Internet
connection plugs into there, and the machines plug into the other side of
the router, or to put a second network card in one of the two machines and
use that machine as the gateway to the Internet.
This will also allow you to properly set up the home network and domain, and
everything should work just fine.

the best approach.


is your Win2K


connected to the


address, and use that


and connect one NIC


broadband connection.


confers no rights.

A NIC costs ~5$US. Surely, you can afford that.
