Cisco ASA Time Based Access-List

This topic is to discuss the following lesson:

Hi Rene,

I noticed on the Time Base Access-list that when I try to configure from 11:00pm to 2:00am it says that has the wrong time range. The way I specified is periodic weekdays 23:00 to 02:00.
What am I doing wrong? Please advise

Hi Alfredo,

If you try this then the ASA gives an error that the end time is before the start time. You should configure it like this:

time-range TEST
periodic weekdays 23:00 to 23:59
periodic weekdays 0:00 to 2:00

Hope that helps!


Hi ene,


How can you block websites by category? Like games using the ASA? Do I need a web filtering system?

Hi Alfredo,

On the previous ASA generation this will be difficult, you can filter URLs but that’s pretty much it. The newer generation that supports firepower makes this a lot easier.

It lets you filter websites based on categories and such.


Hi, Rane
Can you provide some lessons on context base ACL on ASA 5512 firepower? how it works and lab related to that?

Thank you
