Internet Sharing using Win XP

hi there! I know this is out of a topic question but this is the only forum I know who really answers questions, so I hope you understand.

I have 3 computers right now and 1 of them has a dsl connection, I want to share the internet connection of this computer to the 2 remaining pc's that I have I already have a switch ....my questions are

1. Does the computer that has a dsl connection need to have another lan card so i can put the ip address 192.168.0.1

2. Should I only enter the preferred and alternate dns on the 2 remaining pc and set their ip address to 192.168.0.2 and 192.168.0.3

Any idea would be greatly appreciated.

Save yourself headaches and get a broadband dsl router. They are under $50.00 US new, and make things so much simpler.

But if you insist, yes you'll need a 2nd lan card in the router computer that connects to the dsl only, while the other lan card connects to the local computers. Then in the properties for the wan nic, enable Internet Connection Sharing.

I don't know if ICS is available in XP Home. I haven't used ICS in years.

so i use a broadband dsl router how does it work?

1. does the dsl modem connects to the broadband router?
2. should there be a connection from the switch to the router or do i still need a switch for this?
3. what should be the ip address setting?

thanks!

The dsl router would replace your dsl modem. The router and modem are integrated into 1 piece of hardware.

Many routers nowadays incorporate a few ports aswell (4 is normal) and so this can be used as a switch aswell. Or connect from the ethernet port on the router into your existing switch.

Most dsl routers also incorporate DHCP which will dynamically allocate IP addresses to the computers attached to your network based on a series of addresses you specify. The router would be allocated something like IP address 192.168.0.1 as standard and then computers on the network would be allocated addresses sequentially after this (so 192.168.0.2, 192.168.0.3 etc..)

Hope that helps.

This is not always the case. I have separate dsl modem and router.

dsl phone -> dsl modem -> ethernet to linksys router WAN -> <- ethernet LAN connections

Sorry. Just going by what was put up here...A broadband dsl router normally incorporates a modem, doesn't it?
Not wishing to be pedantic....
And alot of the broadband modems supplied by ISP's in the UK are connected by USB, which I don't think is a connection option available on just a router.

No

If you already have a switch, then you can plug the DSL modem into the switch and plug the other computers into the switch and be able to share the connection. Run the switch in bridge mode and use the DHCP from the modem.

However, if you use a switch you will divide up your bandwidth.

A switch is not the same as a router. If your bandwidth is 100mb and you plug two divices into it, each is only communicating at 50mb. A third and they are all at 33mb. A fourth, at 25mb, and so on.

All devices plugged into a router though would all be communicationg at 100mb.

Just a thougt, plug all your computers into the DSL/Router, or attach another router to the DSL/Router.

Well, this is just not correct. Switches don't reduce the connection speed, I don't know where you got that idea.

And if you plug all your devices into the router, why that means you're using a router with a built-in switch, so you're really plugging into a switch.

And if you connect another router to an existing router be prepared for a non-working network.

Sheesh! About the only correct statement was that a switch is not the same as a router.
