Mmm, this is a bit overkill, may I make a suggestion ? Have one local DNS server that can be set up for your local machines and as a cache for name service resolution. In the local name server configuration set your ISP nameserver(s) as forwarders. Set your resolver to look at the local nameserver. Your local name server will resolve requests for your local hosts, and "non-authoritatively" for any in it's cache. Otherwise it will forward the request to the ISP name servers for the answer. When the answer comes back it will cache it and subsequent enquiries for the same resolution will be much quicker. It's what I do anyway, and it works well. -- Regards Cliff To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
