Sharing a Cable modem connection

[TheCure]

I have a cable modem connection through @home. I want to be able to link up my computers at home to each other, and also to share the Cable connection if possible. Right now I have a LinkSys hub that allows my computers to see each other. However, when I connect to cable modem into the hub, it does not work. Would buying the Linksys router make a difference? Also, I can pay for a second IP address, but I am not sure if that is worth doing. any suggestions?

That's because you need some form of proxy, either hardware or software, that provides &quot;NAT&quot; (Network Address Translation), which allows you to share one IP address.

Yes, it is one way to do the above. The other is with connection sharing software such as the ICS built in to Windows, or a third party product such as Sygate or AnalogX.

If you go with a software solution, you will need to install a second NIC in the system that connects to the web thru the modem.

This is a sample diagram of the hardware type setup. (60k Word Doc).

I have heard the routers are a nice way to go.

Currently, I have two ip's thru @home also. But I have a problem with it. So not sure if you want to purchase 2 ip's or not.

Both my ip's share the uplink port thru my dlink Switch, but the minute I try to network both computers. It takes out my internet. So seperately they are ok.. but if I try for a internal network it goes bad really quick.

Hopefully tomorrow I can really sit down and figure it out. If I get it working I will post back and let you know.

Sorry probably wasn't what you were looking for

a router or switch is the best way to go. Linksys makes some really good dummy switches that you just plug in and leave. Or if your looking to learn and have fun the router is a nice way to go.

Other then that what russ said is true and that is a very good doc russ...

Hope this helps...

Same questions over and over! Sorry I guess I am tired and grumpy. If you want to use one IP and two computers with the setup you have now you will have to add a second NIC card to one computer to connect the modem to. Then, If you have Win98SE or better you can then activate ICS. This will be your cheapest way to go from what you have. If you do not like having both computers on in order for the other to see the net then you can get a router. I use an old computer and installed Freesco on it to share my cable modem. Since there are several options you can use to share your internet I suggest you go to here and read up on sharing. Then come back if you have more questions. Also you can do a search on this forum and get allot of information. It is real simple, just click on search tab on this page and search for words like share,ICS,cable,router,etc under the networking forums.

I hope this gets you started.

I have my systems setup through at home also. I ordered the second IP address which made it easier this way either PC could connect without having the main PC on. I have a NetGear hub and the far right slot is for uplinks, I have to push the uplink button for connection to work. I have 4 slots 1+2 for PCs and 4 for cable modem. Uplinking renders 3 useless. Funny thing I have never been billed for the second IP🙂
They even sent me a letter about 6 months ago stating they screwed up and billing would start. I guess they forgot to mention when it would start..
Originally I had 2nd PC connected thru PC1, PC1 had to have 2 NIC,s 1 for modem 1 for ICS. Like I mentioned PC1 has to be on for PC2 to connect this way.
I wonder if setting IP addresses on Both PCs to the same then to hub would work?

i just installed the SMC barricade ($94 at outpost.com) and 2 smc cards (12.95 each at outpost.com.) Both computers have win2000. I have never installed anything that went smoother!
The 3com cable modem had been setup with one computer using usb. The 3com has usb or ethernet outputs. I installed the cards in the 2 computers - plugged the cables into the router and the modem into the WAN port. FIRST SHOT - everything worked perfectly! Networking the 2 computers thru win2000 was a cinch - they now see each other and both access the web. They don't need to both be on. But, if both are on, you can access different sites on each of the computers. No need to buy another IP.

One last comment - ALWAYS LISTEN TO RUSS!!!
