Schedule web url filtering in isa550

Question

Hello,
This is my first experience using isa550 security appliance.  i would like to schedule the web url filters: in example accept or deny some websites or url categories on certains hours, or days.
i see that the schedules can be applied on firewall rules, but i can't see how to apply theses schedules on web url filtering. when i link the web url policy to zones i don't see anything about shedules .
can you help please ?

I can confirm what you are seeing. There are schedules on the Application Control, for example, but not the web filter. One possible consideration with this is though you may want to allow some websites during certain times (Facebook over lunch hours for example) there would probably be blocked websites you would want to allow ever (child porn for example) ever. Since only one policy can be applied per Zone, until multiple policies can be applied to a Zone, you probably wouldn't want to turn off ALL web filtering for a Zone ever.
I'd recommend trying to leverage Application Control instead. You can apply multiple policies to a Zone so you could create a policy that includes everything that is blocked always and another that has content you'll allow during a schedule. The apply both policies to the same Zone and ensure your schedule policy is above your always block policy so that if there's ever a conflict the schedule policy would apply first and allow the traffic during allowed times. That's unless your internal security policies dictate otherwise.
