Network server with 0 configuration

Hi,

I've been looking around for this and still couldn't find any solution
to my *problem*.
What's this?
The thing i need to do is to set up a Linux server that will act as a
router.
That's easy, i know, the tricky part - at least for me - is that it
needs to be open for any internal connection without needing any
config change in the client's computer.
Been it a static ip, dhcp or anything, the server should be able to
"catch" any of those configurations and give internet access to the
client computer.

I've seen this working in commercial solutions, but couldn't find
anything in the Linux world.

Any idea?

I use ipcop and one of the networks is my testing/lab network. All I
have ever done is plug the systems in and tada the internet. but they
have to be setup for dhcp

What is your internal network? Can you distinguish between "client"
computers and "external" ones by ip (range)? Since you have it set up
as a router, I am assuming this is possible. You should be able to
set up iptables, with NAT if necessary to do what you are looking for.

yes I have MY lan which is set up as static ip's and the LAB lan which
is DHCP.

So the lab LAN and the servers with static IP are all behind the linux
router and you want to access the Internet through that box? If so,
you need to set up NAT on the linux router, with the IP ranges. Look
into "man iptables".

Thats right they all run NAT, as all most of the outside world sees is
the router
