Hello all,
I know cisco and others have appliances that will do web filtering. I am curious as to if a Cisco IOS has the capability to filter web access. Here is the scenario:
A subnet in a corporate needs access to only two website on the internet. The IP address of the servers does change from time to time. So to control access to these two website, naming must be used. No other sites or services should be accessible. I am hoping to use an old spare router (2621) to do this.
Can ACL's be done with a name and not an IP and are there other capabilities of a particular IOS that can allow for more functionality?
Thanks

Yeah, you can use NBAR to do this. The best place to look is: http://www.cisco.com/en/US/partner/products/sw/iosswrel/ps1835/products_tech_note09186a0080110d17.shtml
This doc talks about using NBAR to block Nimbda, but is the best NBAR doc I've found.
It will probably be MUCH easier to use use ACLs and keep them updated....

NOW THAT IS INTERESTING!
Thanks for the link. It will take some playing, but looks like it will work just fine.
