Firewall DNS issues

[tspore]

I am working on setting up a Firewall solution for a client.
Basically – to get outside the network we have to point DNS to the firewall – not to the ISP’s DNS server. So the reality is I am having slow DNS look ups to get outside the network. So it appears that the main bottle neck of the firewall is DNS.
Does anyone have any ideas for how to get the clients the ability to look outside the server for DNS?
Thanks!!!

You should run a caching DNS server on your Mac OS X Server and have all clients use it. It will contact the root name servers and cache the results.

If you also need DNS to manage a domain name and public-facing services (a website, email server, etc.) you should look at the Split-Horizon DNS setup.
