Use PC as wireless Ethernet bridge?

At home I have a wireless network, the basis of which is a Linksys WRT54G
router. I then have my PC (running Windows XP) with a wireless PCI card
accessing the router. The PC also has an unused wired 10/100 Ethernet port.
Is there any easy way to set things up so that the Ethernet port on my PC
can be used by another wired computer for acessing the wireless router (and
the rest of the network)? I assume I would link the computers via a
crossover cable, but then what?

Thx

Since you already have a wireless router, just plug the ethernet cable into
the router. Why go computer to computer?

That's what a NAT router does that you have wired or wireless.

http://www.homenethelp.com/web/explain/about-NAT.asp

The NAT router is the gateway device for the WAN (Wide Area Network)
Internet and LAN (Local Area Network) your home network part. Since the NAT
router is the gateway device for all machines connected to it, it provides
the ICS automatically between machines wired or wireless on the LAN. You
can extend the network by plugging a standalone hub or switch and
connecting more computers to it and connecting another hub to that hub and
connecting more computers to it so on and so on. And they will all be able
to access the WAN and see each other and share resources on the LAN,
because the router is the gateway for the WAN and LAN. All you have to do
is plug the wired computer into one of the router's LAN ports or into a
port of a hub or switch that's connected into one of the router's LAN ports
and that's all that's needed as far as a connection physically is
concerned. Of course you don't need wires for another wireless computer and
you just set the channel and some other stuff to make the coputer join the
router on the air waves.

Of course, you'll have to configure the O/S on each machine to share
resources on the LAN.

Yes. internet-local_net-Wireless-PC_one-"ICS"-wired-PC_two.
On the "properties" page of PC_one's wireless card, go to the Advanced tab.
check "Allow other network"...
http://support.microsoft.com/default...b;en-us;306126

PC_two needs a crossed crossover cable to PC_one, and it will be able to
access the internet through your wireless connection.

PC_two is going to get a DHCP address of 192.168.0.something. For going to
the internet you'll be fine as long as your local network isn't already
192.168.0.something. You have no control over the ICS address.

Other PCs on the local_net will see accesses coming from PC_one and PC_two
as coming from the same IP address, that of PC_one. You might be able to
share files if you open the window from PC_two, but not from other PCs
toward PC_two.

Are you trying to go wireless with the second PC without the use of
an adapter card in it? Thinking you can connect to the WRT54G
through the first PC.

If the second computer is near the WRT54G, then plug it in directly. I'm
guessing it is not.

You do NOT need to use ICS for this. Much too complicated.

Just bring up network properties. Select both the Wired and Wireless
connections and right click.

Choose Bridge connections.

Plug a crossover cable between the two machines.

That's it.

That would likely be much better in this case, if there are other computers
on the existing network. Is bridging going to allow a flat network across
the wired-wireless PC, so that all the addresses are in the same subnet?

Uh-oh. You can't run WinXP firewall on either one of the interfaces in the
bridging PC. I always want to run Firewall on any PC on a wireless LAN.

You Sir, are a genius! Thanks... and thanks to all the other responders.

That was introduced with WinXP, and isn't available for Win2000 or earlier,
it would appear. If you are all WinXP, then the only remaining problem is
the statement that you can't run a firewall on the interfaces involved.

After you get it working, I think you should try adding the WinXP firewall.
It might require some setup, depending on what you want going through it,
but I don't like a wireless PC running with no firewall.

I was thinking of setting this up at work, between my desktop and laptop,
but I don't like running wihtout a firewall at work. Too many snooping
systems, all, I'm sure, part of our proactive IT group checking for
unpatched systems, but the probes certainly look malicious.

I was running ICS between the Win2000 laptop and WinXP desktop. Now my
laptop is WinXP, so I could do the bridge, but I want the firewall.

If WinXP firewall doesn't work, try ZoneAlarm. Any PC on the wired or
wireless network in a wireless subnet should have a software firewall,
because any wireless intruder is on your side of the router firewall. You
should also elect trusted servers very carefully in the configuration, and
not allow the entire subnet, which is the default for WinXP firewall.

You can run a firewall, including the SP2 firewall, on the wireless
connection. The second machine sits 'behind' it, so it is OK.

The second machine can be any OS, even Win95. It doesn't know any
different. Only the bridge machine has to be XP. It IS possible to do this
in 2000, although more complicated, and it has been too long for me to
remember the steps.
