VLAN's and DHCP

Currently my friend and I are trying to build a LAN that has multiple
VLAN's. What we want is to have is every single person that gives a DHCP
request to NOT have the ability to see other users on the LAN, but still
have conection to the router for the internet. We figure this can be
done by making about 15 VLAN's, and giving a range in DHCP of only 1 IP
address per VLAN, we're just not sure of the steps on how to do this. I
read somewhere dhcrelay is used to relay dhcp info from one VLAN to
another, but we have no clue as to how to implement it.

What we do have running rite now, is an IPTABLES firewire and a DHCP
server, serving the 192.168.1.x/255.255.255.0 network.

Does anyone have any steps on what should go where and the like?

I assume you have enough bandwidth to support 15 clients -- MASQing?

You'll likely decide it's easiest, best to use a vlan capable switch
that plays nice with Linux. And your hardware will need to be vlan
capable.
Eg., internet --> Linux box/router --> vlan switch(es) --> 15 clients

Take a look at this, scratch your heads many times, understand what
you can, then see if it's enough to get you started. Success will
depend on how familiar you are with vlans running with Linux -- for a
start ;-)

And give google a good work out -- reports of vlan success with Linux
are varied.

good luck,
