Unanswered Question
Jun 8th, 2009

Hi,

What if we need to get in rule to permit certain site on ASA with the sites domain name & not based on IP. Can this be done by just putting in the site name"www.abc.com" or is there any other way.Please help.

Thanks.

I have this problem too.

Hello Thomas

If you want to restrict access through URL's, you need to have a URL filtering software seperately , or have a CSC module with the ASA.. CSC can do content filtering.. With a plain ASA, you can just restrict traffic with IP addresses..

Hope this helps.. all the best..

You may use command show module 1 detail to verify this
