I have 2 PC's on a wireless network. A laptop an a
Desktop. I am trying to share the desktop's wireless
connection with 2 other desktops attached to the first
desktop thru a LAN/wired network. Is this possible? and
how can it be done if so.
I believe that you can do this via Microsoft's ICS
(Internet Connection Sharing), if the hultihomed desktop
is running Windows XP.
However, you will have to configure routing appropriately
on the wired machines, so they understand that there is
a net beyond the multihomed desktop. One option is to
configure your wireless net to be 192.168.0.x, and use
DHCP, and let the ICS-builtin DHCP server give out
addresses and default gateway (itself). The ICS-builtin
DHCP server apparently only works with the network 192.168.0.x
If you have also a connection to the internet, then you
may need to pay attention to routing metrics, to ensure
that the route to the Internet has a lower metric than
the route to the multihomed desktop, so your wired
machines don't send Internet-bound traffic to the multihomed
desktop for transmission into the wireless net (unless that
*is* the path to the Internet).
Best of luck.
PS:
multihomed=having two IP addresses. Your desktop which is
on both the wireless and the wired networks has an IP
address on each, and is therefore multihomed.
