I have no idea what you are saying, can you be more obtuse please......
As far as allowing a specific IP address to access only specific IP addresses, that will work as long as IP addresses you are noting are not in the same subnet which is not controllable by the router very easily.
So if you have user 192.168.25.25 you can create a firewall rule like so which will permit the user to access allowed sites and then the next rule drops all their other traffic, either to other subnets or to the internet for example. As long as these two rules are placed after the default rules and before any other allow rules..........
add chain=forward action=accept src-address=192.168.25.25 dst-address-list=AllowedSites
add chain=forward action=drop src-address=192.168.25.25
How do i add sites, is it by ip or url? For example i added youtube.com but cant connect to website somehow?

Edit: Never mind it worked, had to add the dns servers to the whitelist, thanks again
