Author: 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.

on the firewall they all go through you should be able to restrict outbound traffic on port 80 “except” to certain IP addresses that you want to allow out
Usually you would do this at the firewall. Any decent firewall should give you the ability to limit what is accessible on the Internet.
The other alternative would be to setup a proxy server that would give you more options and flexibility.
Use your firewall to restrict them. How long have you been administrating this?
