I recently just was thrown onto managing a smaller network in the building I live in. Currently, there is a Cisco 1700 series router that does nat, and a dhcp server that is plugged into one of the 3 switches, handing out internal ips and dns servers. I was hoping to switch this around, and put the dhcp box (linux) in between the network and the router for both more security and control. The only issue is that if the network side of the linux machine is performing dhcp, and the router does NAT, should I try to find a way to bridge the connections across the linux machine? or should I disable nat in the router and do it over the linux machine? if I do want to disable nat in the router, what is the command just to have it route external ips? Thanks so much for any help.
