Block a specific URL with Acess Lists

[alexi]

Is it possible to block a specific URL using Access lists, or do you have to use the IP?

TIA,

Alexi

Hi Alexi,

yes you can do it with IOS Routers similar like blocking the "Code Red Worm". Look at http://www.cisco.com/warp/public/63/nbar_acl_codered.shtml#acl

Modify the class-map to your needs, build a policy-map and handle matching policies in the access-list.

URL blocking on a pix is possible only in conjunction with a websense server running. For information look at http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_62/cmdref/tz.htm#xtocid5
