Providing Internet Access to Three PCs in Workgroup

I have three standalone computers accessing Internet with
cable modem and router. I need to place these computers
in a workgroup so that they can share resources, but
would still like for them to continue accessing the
Internet using existing modem/router hardware. I have
installed a new 4-port switch and added a second network
adapter to each PC. I configured static IP addresses (and
subnet masks) for these computers, and configured the
workgroup networking support. Now all workgroup functions
work fine but none of the PCs can access the Internet.

Do I need to configure a default gateway address in each
of the new workgroup network adapters? If so, do I need
to call the cable service provider and get the correct
default gateway address? I would like to maintain the
method these PCs currently access the Internet if
possible. I know that this multihomed configuration is
not the most efficiently way to do this but there are
business reasons that this is being done.

By the way, as soon as I Powered-down the workgroup hub,
all computers could again access the Internet with now
changes to the software configuration.
Any help would be appreciated.

Why did you add a second NIC to your machines? Can you state the business
reasons? Just use the existing ones. There was a recent post between myself
and a poster in the DNS newsgroups that had a smilar situation that needed
mutli NICs. After mutliple attempts to get it to work, he finally removed
the extra NICs and all is working, and securely too. I can give you a
pointer to that thread so you can read up on all the specifics (too much to
mention here).

As for IP configuration, yes, you always need a gateway, that tells the
machine how to get to the outide world (so to speak). If you two NICs, it
complicates it a bit and any multihomed machine can only have one gateway.
The binding order would dictate which NIC to use. If two NICs, you need to
choose.

Was unable to locate the DNS post you mentioned but your
suggestions makes perfect sense. Will remove the switch
and second NIC from each computer and give that a try.
Still a little unclear about the router will be able to
distinguish internal traffic from Internet traffic but
will be ecstatic if this works. Will post results.
Thanks,
Jim

It will. That is what those things "do for a living". :-)
