I want to set up a LAN using DHCP to assign IP addresses to local hosts. My cable modem service also uses DHCP. It appears I must configure my DHCP server to see the ISP's network but mark it "not authoritative." Is this correct? Also, I understand there is still a chance that the ISP's DHCP server will NAK my local hosts when they seek IP addresses from my DHCP server. Is it sufficient for me to limit my server's address range to 192.168.0. or similar? I am using 2 nic's and plan to use IP masquerading to give the local hosts access to the internet.
