[RESOLVED] Moving from Dial-Up (ICS) to Cable Modem

[terryZ]

I have a network (at work) of 4 pc's. One computer (I'll call it "A") accesses the net via a dial-up, the other three (I'll call them "B", "C" and "D") connect through "A" using Internet Connection Sharing (ICS).

Yesterday we had a cable modem installed from Comcast.

I connected machines "B", "C" and "D" to the cable modem.

I thought I would have to run the Network Setup Wizard to connect these to the cable modem but, per the tech's instructions, I just "repaired" the network connection on all three. They all then searched for a new IP and connected to the net through the cable modem with no problem at all.

I refrained from doing anything to the "A" machine because it is configured to run ICS.

What, if anything, do I need to do to the "A" machine to de-activate or disable the ICS before connecting it to the cable modem? Should I run the Network Setup Wizard or is there a simpler procedure?

Thanks in advance.

Hello zeszut,

A router is best for sharing a broadband connection to multiple computers. With a router, your computers will be safer. A router will block incoming traffic on all of the computers on the network. If you have a router there is no need for ICS to be enabled on the host. If there is no router, then you need ICS for Internet Sharing.

Sorry. The "modem" is a "router/modem". It has 4 ethernet connections.

I did manage to disable ICS on this "A" machine. Everything seems to be working okay. I just wasn't sure if there were any other setting that needed to be changed.

Thanks.

That is really all you need to do. You don't need to run the Network Setup Wizard. The computers should obtain an ip address automatically from the router. Just plug each computer to the LAN ports on the router and you should be good to go.
