Connecting multiple IPs through one modem

I have SDSL service through an SDSL external modem. I want to connect 3 or more computers, all with different IPs through the modem. I can connect the modem to a hub that connects to all the computers? Will that work? or do I need to get an SDSL/cable router?
Thanx...
 
depends on the hub at that point. Most hubs have a little switch or 2 ports connected and you use one of them (the "uplink" port). If you use a stright cable you will need to select the crossover port setting. If you use a crossover cable, it will work on any of the ports (and make sure the uplink port isn't used or is set as a normal port). The easy way to tell is if that port is lit up on the led. Good luck, it should be easy to do.
 
Or you can enable Windows Internet Sharing (or some similar routing program) that will allow you to share your internet connection. One of the computers has to be the gateway (ie has the Internet Sharing program running and connected to the internet as well). Then on the other computers, you have to specify the IP address of the gateway for the other computers to know where to send information to get to the internet. 🙂
 


<< I have two IP's and run a 10mb hub off the cable modem. See the Network Diagram for details. All cables are stright-through. >>



I never knew cable companies used Dynamic IP's for their users. DHCP server yes, but not dynamic ip's. What ISP do you go thru? Also, with 2 separate IP's I have heard you get 2x the bandwidth as opposed to sharing 1 ip thru a proxy... True?
 
I have two IP's assigned to my cable modem. They are subject to change at anytime, so they are dynamic, yes it is DHCP, if they were permanent they would be static.

My line gives me xxx for bandwidth, doesnt matter if I have 1 IP or 10 IP's, same pipe.

ISP is Road Runner in Texas
 
You need a crossover cable from the modem to the hub. I have the same setup. I have two IPs, one IP gets shared by my whole house through a linksys router, the IP connects to my gaming machine directly to the hub.
 
Why do you need a cross over cable? I use a straight-through cable with no problems. Or does your hub not have an option for using either stright or crossover? Mine does, thats why I went with the straight cable, already had it on hand.
 
It depends on your modem. On my modem, I have to run a crossover cable from the modem to the uplink port for things to run correctly. Some modems use a straight thru cable.
