Hello,
I just got 2 new room mates that wants to share internet. Prior to them
moving in I was just using a switch between my 4 devices (2 computers, xbox
and dishnetwork). I configured the router and I disabled dhcp and that works
fine. But then I realized my ISP only provides 5 IPs (DHCP, not static), and
just between my stuff I'm already using 4.

Ideally I would like my devices to obtain DHCP from my ISP. Then the router
could get the 5th IP from my ISP and provide DHCP to the wireless devices.

Here is my physical setup
Modem plugged into switch
Router plugged into switch
All of my stuff plugged into switch

I would like to keep all of my devices separated from theirs. So the shares
on my 2 computers wont be available to them, and their shares or whatever
they may have will not be available to me.


Another reason I'd prefer my stuff to not be on the router is because I
don't want to be behind the router firewall. All my stuff is locked down and
I don't want to have to deal with NAT, but on the other hand their stuff
could probably use it just to be safe, d


Is there a way I can configure the router without having to plug the modem
directly into it, yet prevent it from trying to DHCP my stuff and only DHCP
the wireless connections?
