need help setting up a network

Cogman

Lifer
Im running mandrake linux right now, and am trying to figure out if it is possible to set up one network with 2 wireless cards and 2 wired cards. there is a total of 3 computer, and I want them all to be able to connect to each other and the internet. Computer 1 I want to be able to connect to the internet nomatter what. the current setup is (but can be changed if you think it needs to be.) looks something like this

computer 2
_______________/
______________/___________________)))computer3
_____________/___________________/
internet--------hub----------computer 1(((

[edit]Dont mind the _'s they are place holders spaces dont work.[/edit] Im using the ))) and ((( to represent a wireless connection. also, computer 3 is a laptop and cannot recive a wired nic. is it possible to just set it up like this? If I am going to have to buy something Ill probibly end up getting a wireless PCMCIA.

[edit] BTW I have a DSL connection, and So its just running threw a cat5 cable, I also cant give computer 2 a diffrent IP and a seprerate connection to the internet. computer 1 need to be the only one with an ip viewable to the world. [/edit]
 
First off, does your DSL connection actually allow you multiple IP addresses? If you use a broadband router, this is very easy, even if it doesn't.
 
Well, I can connect to them and get an IP via dhcp (so I guess yes) but they strongly discourage agenst doing that. Besides that, I dont know that I would be able to connect to the other computer if I did that.
 
I guess I don't understand. Either your ISP allows multiple IP addresses, or it doesn't. If the "strongly discourage" connecting multiple computers, my guess is they don't. A broadband router is cheap, and an excellent way to solve this problem. BTW, your laptop can accept a wired Ethernet connection if it has a PCMCIA slot, and it can also accept a wireless connection. BTW, I have a bunch of machines connected to my SMC router, including W98, W2K, WXP, my TiVo, and also RedHat Linux 9. They all have access to the Internet without any difficulty.
