Q: I have a SDSL SDSL services via external modem. I want three or more computers, each with different IP addresses via the modem. I can connect the modem to a hub that connects all computers? Will that work? or do I need an SDSL / Cable router to get? 977 503 Dan .
Best Answer: There is absolutely no sense in doing this. Why subnet down to only 32 IP addresses (27 bit subnet mask) to begin with?
I would use a single router and network switches; as set up you need to set up routing tables to communicate across the Local Area Network and all you are doing is creating work.
Re: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.
Re:My hub has an Uplink port, so I should be able to use straight through right? from the modem to the hub?
Re: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.
Re: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.
Re: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.

Re:<< I have two IP's and run a 10mb hub off the cable modem. See the Network (http://home.hot.rr.com/sgallery/network.htm) 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?

Re: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.
Re: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.
Re:Also, what cable would I use to connect modem to hub? Cross-over?
Re:ThUuuper, thanx a lot.
Re:It'll work as long as your ISP has given you more than one IP.
