Vivek, What you're after and the approach Jason mentions are a very, very common setup. Once you've done it a couple of times, you'll find it's a total piece of cake--especially on OpenBSD, since so many of the things you need are available and just need to be turned on. I think setting an OBSD machine up like this takes me something like 15 minutes now from start to finish. Getting there the first time will likely take you quite a bit longer. If you're looking for a good primer on DNS, look here: http://www.langfeldt.net/DNS-HOWTO/BIND-9/ It discusses all the stuff Jason mentions in good detail and should put you on the right track. Kevin P.S. Skip the reverse DNS part unless you really need it. That part can cause more headaches than it will likely ever be worth in a smallish network like the one you describe. P.P.S. No, you don't need to register a domain if you take the approach Jason & langdeldt.net describe for your local network -- http://www.ebiinc.com : EBI: the background screening experts Leaders in corporate background checks, worldwide.
