sharing a LAN internet connection

hello members,
i dont know much about networking but trying to learn it. right now this is my query.....
i have a LAN internet connection and my ip address is 10.10.2.39 in the network. i have 3 computers here but the internet connection is connected to only one system. i wanted to network these 3 pcs such that i can use the same internet connection. i bought a Hub and already done the LAN for these 3 pcs. but the problem is i have been assign 10.10.2.39 ip from my ISP and the username password given to me will work only with this ip address. now i have connected this LAN (internet) cable to this HUB but i am not able to access the internet from my other PCs and it works only with that PCs which has the IP add 10.10.2.39. When i make the IP address of the other 2 PCs as 10.10.2.39 it says that there is a IP address conflict????? Does anyone have a solution to this problem. or is there any other way to do this.

NAT (Network Adress Translation) is your friend ;)

You will need a router for this, or let one of your computers act as a router in this case.

Cheers.

use computer with 10.10.2.39 IP as your gateway.
What OS are you using? If it's windows XP, just use the networking wizard on the computer that has internet access....make sure yoiu select the option that says to allow other computers to connect to the internet thru this computer.
If you're looking for understanding.....google for "gateway" or "proxy" or "internet connection sharing"
Have fun ;)

As instronics has mentioned, a $60 router will do the job very nicely. Go to your local BestBuy or Comp USSR and grab a Linksys BEFSR41. The setup is easy and you'll have all 4 hosts on the internet at the same time.

Just to point out not all isp's support home networking, Aol for instance will not let you setup ics.

The Linksys router will allow you to spoof your MAC address should your ISP be a bunch of cheap ****s and force MAC auth. :)

Where there is a will there isa way ;)

hum.. doing that inst a kind of hacking?....
if ISP doesnt allow you to do home networking.... just thinking...

cacosapo,

Not really a kind of hacking. It would be a breach of the terms and conditions of service, sort of breach of contract.

It is a bit of greed by the ISPs, they want to try to prevent small businesses getting a private connection then setting up a network which they would charge more for if it were a business connection.

My contract specifies a maximum of 1Gb downloads per day, so as far as I am concerned that is what I am paying for, and how I use it is up to me.

The ISPs, however, are juggling with resources and typically share a private connection with a lot more users than a business one. Over here, that would probably be 50 customers.

If the people on my link all set up 4 machines and all had children who come home from school and immediately went on the internet, I would be sharing with 200 people, which is a far different contention level from the one I signed up for. If they all start up Kazaa and start downloading, I would probably be better off using my 56.6 connection :)

The ISP is playing a gambling game and betting that all 50 customers will NOT try to get their 1Gb at the same time, and that most (like myself) will get nowhere near it. At full belt continuous downloading I would hit my limit of 1Gb in around 5.5 hours. In this session, I have been on for an hour, and actually used 1.9Mb. So usage patterns are important, and to ISPs a home network + "kids" ="kazaa" :)

The issue is basically bandwidth and how much money they can milk out of it.........the usual story?

Just my thoughts

Although Ive already did some kind of "obsfucation" to avoid ISP to "see" more than one computer sharing the adsl connection, i know that is AGAINST the conditions of service. Some ISPs here have a clause that say "...You cant use your connection for more than one computer ....."
If you avoid detection like spoof mac address or hiding O.S. signatures you are breaking a clause so... for a general audience, you are "hacking". (just speaching as public in general)

Ive added this comment (and the previous one) just to make newbie readers aware that some actions on adsl/cable links can be "read" by ISP as a kind of "outlaw" activity...

not even if you set the TCP/IP settings manually????
I knew there was a reason I don't use AOL :D

I guess I'm lucky in that my ISP gives you an option to pay extra money to have "home networking" service....if you don't go with that option you can still have a network, just no tech support for networking issues.

Please tell me you're not actually paying for that tech support bullshit....



THe way I see it, I'm renting a DSL line. Whatever I do with it, is my business. Whatever I connect it to is my business. Verizon can kiss my ass. I'll pay extra when they stop charging me $ .50 for all them little * things each time I use one.

dear D0pp139an93r:
I agree with your arguments. However i dont wanna to pass to everybody here that is a "legal" position. Some of your comments can lead newbies to take actions that be dangerous for them (but maybe not for you )
For example:
Verizon broadband service agreement:
"e) You may not use the Broadband Service to host any type of server personal or commercial in nature."
This is a very common clause around the world when talking about HOME connections. I have this on my contract HERE.
However i run a web server on my home networking and i can be acessed from Internet (banned by contract)
I can have my link disconnect and contract ended due to this. But i still try to hide this server (and im kinda a sucessfull on that job)
but its against of contract. period. it s not legal.

If you go to network connections and try to get to the properties of your Aol connection, you will find that you can not. So the answere is no.

I supose though if you new exactly how the aol software made the connection for you, the strange tunneling and loopback protocal they use. It maybe possible to set a connection up manualy.

But then that would be Hacking.
