I only want my vnp to access certain websites

Hi All

I am new to Mikrotik. I have setup a VPN and have got access to the internet. But I now I need to block everything except for 20 site’s that are work related. I have setup Web proxy and it is blocking sites that i have nominated. But I cant find a way to only allow approved sites. Can anyone point me in the right direction.

Using a R433 with 4.50 Os.


Regards

Instead of blocking sites in the web proxy access rules accept the sites that are permitted and then add a drop all rule at the bottom.
