How to setup PIX to use DNS?

I want to setup my PIX to resolve DNS. Is there a way to do this?

Thanks,

Jason

No. Otherwise security policies configured on the firewall that relied on name resolution will fall prey to a simple DNS spoof, hijack, or server compromise and would render all security configured on the firewall useless.

Thank you for the reply. Then I assume there is no way to block URL's with out having to block by IP only?

No. The Pix cannot filter at the URL level by itself. You can have it forward the requests to Websense or N2H2 for such functionality using the [url filter] feature.
