I can hardly understand what you are saying, but I'll give this a shot.

You should setup as follows:

Cable modem---->router---->each individual PC

No need for multiple cards. If you don't want to give access to the server, just don't share anything on it.

I'm not sure what you mean by "not sharing" the internet connection. If I'm not mistaken the whole point of this is to share the internet connection, no?

What you would then do, is set your router to automatic IP from your ISP, and set it up to be a DHCP for your systems. Set each of your systems to obtain auto IP from router and you should be all set.

thanks for reply...ill try to explain...i want 2 networks with router one that lans the 2 pcs and one for the internet with no ip sharing because we all have different or our own ips....this will be on winfirst so i will not need modem.....is that a little clearer?let me know...

WOW!! I will to give this a shot, still after the second explination I am still confused. If you are on two different networks you will need two NIC's.

What operating sys are you running and let us know what the main goal you are triing to reach.

explain each lan. I believe you want two lans. One for internet and one for server. What is the difference if you are on the same subnet or not. If you can lock the server down? Like I said earlier and JFUNK. I feel so confused. (and it is not the network part it is the understanding of the question.

Okay, number 1, if you want TWO networks, you need TWO cards in each. You can't have your router "create" two networks if thats what you're asking. I'm really still not clear on what this whole two network thing is about. Perhaps if you try to explain what it is you want to do....

Second, If you want more than 1 IP address from your cable company, you will have to talk to them about that. They cost money. Your machines on your network will still have their own IPs on the network, but your cable company is still only sending to one IP. Your router is taking that traffic and splitting it up between your machines. The cable company doesn't know how many PCs you have, it only sees the router.



<< this will be on winfirst so i will not need modem >>



Not sure what you're talking about there.


BTW, about the two networks...if you want all three machines to be able to use the internet through your router, they are still gonna have to be networked. Plugging machines into your router IS networking them. I really can't see the purpose of your second NIC in the other two machines here.

thanks for the info...im cofused too!!i just want to have one network card in each and not share the internet-im ok with paying for the seperate ips and be able to game on each one pc to pc...i think maybe ill buy a switch and save money because it will be easier to setup because i dont need to share the internet...and i can always specify ips tp connect for online gaming right?

 

[CtrlAltDel]

ok.it hit me....what the main thing is is i want to set up this system so that the router will recognize the sperate ips!!can it be done or would it be easier and cheaper to just get a switch because im not sharing the internet!!??

thanks

Okay, I think I see what you mean right now. You want to network through the router, but DO NOT want internet on all the machines?

Well, I suppose you could setup your router to block all the ports going to the machines you don't want on the net, but I don't see any reason to. Is there a reason you don't want the machines on the net?


Your machines are going to have their own IPs as far as your network is concerned no matter what. What the router does is it takes its own IP address (as assigned by your ISP), then it assigns IP's to your machines. Those IPs have nothing to do with your ISP, it doesn't even know they are there. The router can then break up the info comming in and send it to the different PCs depending on which requested it.

sorta what i want to do is take the 2 pc and only have 1 nic in each and let the router do both lan and internet with 2 seperste ips!!!...i hope that seems clearer?

Your explanation is still unclear.

1. Are you saying that you want 3 computers connect to the router, but only your computer capable of accessing the Internet?
2. If not, who is supposed to be able to access the Internet?
3. Also, is the server going to accessible from outside the LAN? i.e., Will other people be able to connect to the server's web server, ftp server, etc.?

Not sure if have the features to do this on the router, but maybe you can just block the incoming/outgoing packets (at the router, not the inidivdual computers) to/from the "not connected" computers (aka a firewall)?

Okay one more person to add to this confusion embeded thread!

First I think you would be able to ask the questions you are needing answered in a way that people would be able to understand if you read a little bit. Try http://www.practicallynetworked.com and the Anandtech Networking FAQ's. My understanding from all of this is that you want Separate PUBLIC IP address for each workstation on the LAN (not including your server). #2 You want an internal PRIVATE IP LAN for your workstations AND server so that you can game/file share etc. IS THIS CORRECT?

If so you can do this several different ways.

If your cable provider supports it you can purchase additional IP's from them and put the network out from your cable modem into the uplink port (or use cross-over cable into a regular port) of a standard hub or switch. If the don't provide the support to issue multiple IP's to each cable modem then you will be required to get an additional cable modem for each computer that needs access.

2) AFAIK, you can't assign multiple IP's to the same nic if your receiving one of those IP's via DHCP. So then you would have to pay extra for a static IP address (if offered). Then you could assign a private IP address as well as the static IP address to the single nic's of the workstations. The server would have a single nic with only a private IP (192.168.x.x or 10.x.x.x - most common) whereas each workstation would have both a public IP as well as a private IP. To me all of this is a waste. I use NetBEUI to connect my pc's at home to file&printer share with TCP/IP unbound to Client for MS NW & F&P Sharing. I receive multiple IP's from my cable provider via the uplink hub method. Both computers can still play multiplayer games (TCP/IP based) but not with the LAN method.. I have to input the IP addresses manually due to the fact that both computers 3rd octet's are different.

I think other people would be able to help you if you would spell out EXACTLY what you have and what you are trying to accomplish. Is this for security? or is it a REQUIREMENT that you be able to start a game server and the other workstation's just search for a LAN game?
