Scheduling

Hi

I would like to know how to open a website for an IP at certain times during the day as we are a big office and I would like to open sites like youtube and facebook after 18H00 in the evenings.

My suggestion would be to use the web proxy, set up deny rules for *.facebook.com etc and use scheduler to enable/disable the proxy at the times you deny/allow access.
Either configure each device to use the proxy, or use a firewall rule to redirect http traffic. Either that or setup dns entries for www.facebook.com to 127.0.0.1

Adyb

toggleable(by sheduler)static NS entry/blackholing would look more reliable.
don’t forget to filter outgoing NS traffic outside your router/network, btw.
