How to use second network card for internet sharing?

[gz]

Hi, I am using Win 2000. On the PC1, there are two network cards. One is
wireless NC1, which is connected to a wireless rotor and the rotor connected
to a cable modem for internet. This NC1 is asigned to IP 192.168.0.100 by
the rotor, the rotor is asigned to 192.168.0.1. What I want to do is to let
a second PC2 connect to PC1 using the second network card NC2. I do not know
how to setup PC1 for this purpose.If I configurate the wireless card NC1 for
internet sharing, its IP will be asigned by windows to 192.168.0.1 which has
been used by the rotor. What can I do?
Thanks for all reply!

Depends on the exact OS, and whether you wish to
allow the other machine to access the Internet through
PC1 (and thus through the router).

If I configurate the wireless card NC1 for
internet sharing, its IP will be asigned by windows to 192.168.0.1 which has
been used by the rotor. What can I do?

Assuming the Win2000 is NOT a "Server" (product)
then you cannot do this easily.

You can reconfigure most routers to use a different
set of addresses, or you can configure simple "routing"
on the Win2000 PC1 since you don't need "translation"
there. Translation is the major feature of the "ICS"
(Internet Connection Sharing).

Such routing is configured in the registry I believe, or
perhaps with NetSH.exe but I seldom actually do this
and most people who have the need don't usually want
to get involved -- Server product does this easily in
RRAS but Workstation has to be manually configured.

You use one Nic and forget the whole idea.

Thanks for your reply. However, I am not quite understand what I can do as I
am not familiar with network. I tried to use a different set of addresses on
the roater, but windows 2000 pro just doesn't let I set the NC1 for internet
connection sharing because the LAN is already set to dinamically obtain IP
address.

That's ok, we don't always know how much to explain
until we answer the basic question and see what new
questions you have.

I tried to use a different set of addresses on

What happened? Does your router support changing
the addresses it uses on the INTERNAL network?

Most do. You may have to read the router manul or
post a question to the vendor of that router or to a
list that deals with your hardware. What is the make
& model of your router?

but windows 2000 pro just doesn't let I set the NC1 for internet
connection sharing because the LAN is already set to dinamically obtain IP
address.

That is true -- Windows ICS doesn't support that change,
so this is why you may wish to change the ROUTER (which
usually do support such changes.)

Also, does the router have more than one internal port?
Many such small routers also act as Ethernet hubs where
you can plug in from 2-8 local machines.

If not, consider purchasing an Ethernet hub (these things
only cost $20-$40 these days). Then plug the router,
and both PCs all into the hub, using the same range of
addresses: 192.1.0.1, .2, .3 etc.

Finally, if you are willing to LEARN a bunch of stuff,
you CAN make the Windows PC act as another router
WITHOUT using ICS. This is manual and requires
editing the registry.
