Is there a way to "forward" DNS requests from an OS X machine to an ISP DNS server? I use DHCP on my machines, but for some reason the DHCP server doesn't provide name server addresses (unlike on Windows, where that stuff seems to get populated), and I would like to have my gateway OS X machine run DNS which delegates to my external DNS, then have all of my other machines configured to use the gateway machine for DNS.
Is this possible without a lot of work?
