Network Subnetting
Hi, How do i setup subnetting on a linux box? i am wanting to split up a network into different subnets, for sales, service and admin so they can see each other just not the different groups, i have read lots about how it works just no how-to guides. If anyone has any clue please help!

Re: Network Subnetting
Can you blank the linux box and install another distro, if so, look at http://www.freesco.info/.

Re: Network Subnetting
Are you using the linux box as a server or a switch?

Re: Network Subnetting
The point I was making is that subnetting is a networking thing (usually through a switch), rather than a server thing - you usually need multiple switches, or a switch that supports VLANs.

Eh? VLANS and Subnets are two different things, one is layer 2, the other layer 3. A subnet can run over multipe VLANS, and a VLAN can conain mutiple subnets. They don't have to correlate with each other at all.
Bennylaball, what your trying to achieve is straightforward(ish), your linux box becomes a router, each network card will belong to a different (sub)network, you then the rules about what protocols to pass between each interface.

Re: Network Subnetting
<my bad>
I had just finished working from 7:30am until 10pm, and my brain was frazzled (and I was having a scotch to unwind).
Thanks, Jon, for correcting me, and putting Benny on the right path.
