Folks, hopefully this is an easy one. &nbsp;<br />
We have a Pix that we are trying to limit outside web browsing to a few web sites. &nbsp;I can set up the ACL with no issues and it works with no complaints. &nbsp;Then the web site address changed and no access to the web site.<br />
<br />
Is there a way to list just the DNS name of the web site in the ACL and have the Pix box do the DNS resolution on it's own? &nbsp;It would save a tremdous amount of &nbsp;time instead of listing the IP addresses of the web sites (Yahoo Maps happens to be one of the sites we are constantly changing).<br />

Dan you use DNS entries in Pix Access Control Lists?

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
