I need to restrict internet access to just a few websites at ~20 locations. The locations are retail stores that need internet access to HR websites and company websites, but I don’t want them surfing the internet.
The stores have connections back to one point (a sonicwall firewall/router) which is where they gain their internet access. I would like to keep from having to travel to each store to change settings on each computer. Is there anyway we could limit internet access in this way.
