Search Again: Re: Only allow certain clients to do lookups From: mattb Date: Tuesday, October 26, 2004 Time: 10:33:13 pm Why not just block port 53 (in) at the router so only internal clients can use your DNS server? Do other name services need to contact your name server? Allow your ISP's name servers access (in) through your router. You could also do this with "firewall" software on your computer. (Mac OS X's built in FW can be used, for example).
