icf (internet connection firewall)

[Guest]

I presume that the icf to be configured requires that the network computers
are connected to the internet, but if I use a router ( a residential gateway
) I choose that each computer connects to the internet through the router.
In that case the Windows firewall that is configured on each computer
protects the computer?
Thank you.

I'm a little confused by your post. You don't want to use Internet
Connection Sharing or the pre-SP2 Internet Connection Firewall with a
router. Here's what you should have:

1. You have the router, so all computers get the Internet and the local area
network through the router. You can have the router act as the DHCP server
and assign private IP addresses (ex. 192.168.1.xxx) or you can manually
assign static IP's. For a small home network, automatic IP/DNS is usually
the way to go.

2. Each computer needs to have a firewall installed. If you have XP, you
should do all necessary preparation and then install Service Pack 2. You
would then use the SP2 firewall with File & Printer sharing enabled if so
desired. Do not attempt to install SP2 without proper preparation. Post
back if you want help with that.

3. On each computer that is not running XP SP2, you need a third-party
firewall installed.

Post back with a better description of your network and your problems if you
want more help.

I have configured a small home network with the network set up wizard. All
the computers run Windows XP pro , all of them are updated with the service
pack2. When running the network set up wizard he looks for a shared
connection on my network. Detecting one the set up wizard recommends to use
that shared connection. I prefer to use the "My computer connects to the
internet through a residential gateway or through another computer" option ,
because when the computers are not connected to the internet I can still use
the shared resources of my network. Choosing the recommended shared
connection when the computers aren't on the internet I cannot use the shared
resources. Having choosed "this computer connects though a residential
gateway" I continuously receive the message if I want to turn on the ICSF. IS
there something wrong with my computers ? The recommended shared connection
doesn't allow shared resources when the internet connection is down? Two days
ago one of my computers was completely controlled by someone and it had a
terrible crash that I'm trying to recover with the recovery console

Thank you for your time

Normally you would choose the residential gateway when you have a router. I
don't know why you are receiving that message because you shouldn't be.
What is the make/model of the router?

If one of the computers on the network was "completely controlled" by
someone, then there is a high probability that the other computers were
also infected. It would be wise to delay setting up the network until you
know for sure that all computers are completely clean. Doing this on
multiple computers can be complicated. It may be more sensible for you to
have a professional come on-site and sort you out.

the router is a BEF11SW4 Linksys cable router. The modem is a Motorola SB
4200 cable modem. On the computer from where I'm contacting you I identified
and deleted on the shared folders , on the computer management shares a non
microsofot file. Maybe you are right and I will contact the microsoft support
and my computer manufacter support.

Thank you once again.

Maybe I'm right about what? I didn't mention anything about Microsoft or
your OEM's support. You need to hire a professional computer repair person
to come on-site and straighten out the mess. There isn't going to be
anything Microsoft or OEM telephone support is going to be able to do about
your possibly infected machines.
