block specific websites from ASA

Can i block some websites which i know their ip addresses from ASA and how?

Hi,

Yes, you can block the specific websites. Apply the access list with source as your subnet destination as the specific websites and service as IP and the action to deny.

Place the deny rule on top of the permit rule.

I have tried to do it on the gui that exists in th efirewall but it didn't work

deny ip for any as source
and the destination 61.151.253.88 during port 80

Hi,

Make the service as IP and place it as a first rule. Let me know what is the URL which you are trying to block.
