Ok I got two computers that I want to share internet. I have a switch with my main internet connection in the uplink, then I have each of the computers connected to the switch. The computer i'm currently on has internet, and now I want to give the other computer internet also, what do I have to do to accomplish this? I have no network/IP settings on the other computer yet because I just barely finished installing it, and I want to get a few answers before I continue.

Picture at the bottom of my network so you can see what i'm trying to do.

argh, that's the problem, I can not find the "enable internet connection sharing" checkbox ANYWHERE in XP.

ah crap i just read this.

You should not use this feature in a network with other domain controllers, DNS servers, gateways, DHCP servers, or systems configured for static IP.

When you enable Internet Connection Sharing, the network adapter connected to the home or small office network is given a new static IP address configuration. Existing TCP/IP connections on the Internet Connection Sharing computer are lost and need to be reestablished. For example, if Internet Explorer is connecting to a Web site when Internet Connection Sharing is enabled, refresh the browser to reestablish the connection.

To use the Internet Connection Sharing feature, users on your home or small office network should configure TCP/IP on their local area connection to obtain an IP address automatically. Home or small office network users must also configure Internet options for Internet Connection Sharing.

I have a static IP on my computer, and don't want to buy another IP for the computer. Also I want them to be networked, with two additional computers I have (one with internet, one without). So that's a total of 4 comps, 2 with internet, 2 without, which is why I want internet sharing, and I also want them all to be networked to each other.

Damn this is confusing.

Buy a router. Linksys has decent ones for under $100.

The basic of sharing without a Router is to use Software NAT for the Routing.

Windows includes such software it is called ICS.

You put two NICs in the main computer one NIC in any other computer.

The connection is: Modem ? NIC1 (in main computer). NIC2, in main computer is connected to the Hub

The following links will give you info on how the configure that whole thing.

Windows XP Internet Connection Sharing USING ICS.

ICS works, but it is quirky, and sooner or later it will give you trouble

Want to know the general Idea read this:

Thank you very much Jack.

The thing is, I don't really care that much if those two computers have internet, I just want all my computers to be networked with the two computers that I have IP's for to have internet. I tried BSing IP's for the server but they're all taken.

Basically I want a network with the two computers that have IP's to have internet. I've been trying that though and nothing seems to work, which is why I started on the internet sharing.

The two IP's that I have are:
24.221.252.xxx
24.221.252.xxx

And my other two computers don't have any IP's, so how do I go about networking two comps with IP's and two without?

Sorry if my posts seem all scatterbrained, I have so much going through my head I don't know which to concentrate on :)

Throw a second nic in each of the internet connected computers, plug them into a switch/hub, use internal ip addresses, and then plug the other computers into that switch/hub. That will give you a nice little network, but the other two machines wont be able to use the net.

n0cmonkey,

Would that work with my network? Here is what my network looks like, the two computers with internet are plugged into different switch/hubs. So i'm not sure how works.

Im not sure if it will work with that configuration. What I would do is plug the 2 machines you want to have internet access into the outside hub. Then network cards coming back into the switch with the rest of the computers. At home I have 1 computer that NATs the computers behind it. All of my machines have internet access, but only the one is on the outside (actually its more complicated than that, but it would be tough to describe). The outside machine has 2 nics and is part of two networks, the internet and my internal network.

Ok this sounds like what I want, except I don't care if the other two computers have internet or not.

So tell me if this would work.

I put another nic in each of the computers with internet, and then i'll be connected to both the internet, and my internal network?

How do I go about giving myself an IP or whatever so I can also see the internal network in addition to my internet IP? I'm assuming I should use a 10.x.x.x or something.

Thank you I really appreciate it.

internet -- hub -- internet machine 1----|
...................\.........................................switch----other machines
................internet machine 2--------------|

The internal connection (the switch) would need internal ip ranges (192.168, 10, 172.whatever). The internet connection would use your static/dynamic ip addresses.

I noticed in WinXP, in TCP/IP properties, if you set it to choose IP address automatically, there is a tab that says "alternate configuration". In there it says "if this computer is used on more than one network, enter the alternate IP settings below."

What is that?

It sounds like network profiles. I dont do Windows really so Im not positive.
