Sharing internet connection w/ one IP Address ?

[joshg]

Hey I'm looking for cheap possible solutions to set up a small home network. The internet connection only has one external IP address possible, which is dynamic and not static. Sort of like setting up private internal IP addresses to go through a hub or something which supplies the external IP... main question would be how could I set it up to connect ? Or what are the other options. btw the connection is SBC DSL

edit: from my post below, here is a detailed description of the structure so you don't have to scroll!

OK here's the structure:

1 PC running Windows 98SE w/ 10/100MBbs onboard Ethernet adapter, currently connected to the DSL modem directly
1 PC running Windows XP Pro w/ 10/100Mbps Netgear NIC
1 Laptop running Windows XP Pro w/ 10Mbps 3Com PCMCIA XJack NIC

I think the easiest way would be to not have to install any more NICs into computers, which sounds fine for me Anyway, I can get 4-port hubs for cheap... only problem is I don't know if I should just get a 10MBps one or go all out with the 100Mbps one. I mean, DSL isn't connected at 100Mbps, closer to 10Mbps / 8 = 1.25 MB/sec, right? Plus the lappy only has a 10Mbps NIC anyway

What I am wondering is if I just get one of the cheapy 4-port 10Mbps hubs, would there be a way to use this device with SBC DSL? There will only be one outside IP, so I don't know if a hub would do the trick, unless they support something like NAT? Or would there be one host/server computer connected to the hub wich actually controls all of the outflow for the main IP ? hmm... if someone could give more insight concerning this exact situation, that would be fine by me

thanks again!

Is it a DHCP address, or a PPPoE address. A simple solution could be a home router/gateway. If you don't want to do this, I recommend you run a Linux/Unix router/gateway to handle the PPPoE addressing. If you want, windows 2000 server (maybee pro too) has the capabilities to run NAT. If you were to use a computer, you would need 2 NIC's. One for handleing the incoming connection, and the other to hand out IP's.
BTW, I talked to this guy from SBC last night, and he said you can run a single static ip... which reminds me I need to call their emerging products number (1-888-884-2375).

Here's a little HOWTO written by JackMDS, I found it useful

hmm... Let's see it is using PPPoE, in fact I remember I set up the computer to use RASPPPoE, which is basically using Windows DUN instead of that proprietary SBC crap. There are going to be 3 computers in the network set up like that, so I don't know if the 2 NICs in one computer could be an option. Hubs are cheap, would there be any way that I could use a hub to connect directly to the DSL modem?

Thanks for the input

cheapest way is to use internet connection sharing assuming your using win98se/me or win2k. Im using ics with my win2k box as the gateway with no problem. and its quite easy to setup and free. u just need to enable it and then set your gateway ip address to the computer that is sharing the connection (main computer recieving the dsl connection) to your client computers as well as provide proper private ip addressing... oh yeah woops, u need 2 nics in your host computer, hell just buy a cheap hardware router. they work great and are pretty cheap these days. i reccomend the smc barricade which is what i used when i had a cable modem in my old apt.

Well, the 10/100 hubs are pretty standard these days. Would it cost much more for you to get a 10/100 hub? This would really come in handy if you ever need to move large amounts of files between the two computers. Or even a couple large files I guess. If you ever transfer stuff like that, you'll probably find the 10MBps speed to be crawling along
