first of all I beg your pardon for my english.
I am quite new to RouterOS (6.37.1 on RB951Ui-2HnD) and the built-in firewall.
I would like to implement some simple (?) rules to drop all internet traffic and ports and permit allow only some specific websites.
Is it possible? I have searched on the web and I have not found anything.
Thanks in advance for your replies.
Yes, you can block all the traffic & ports by creating this simple rule.
Block All & Accept Exception Rule
chain=forward action=accept src-address=X.X.X.X dst-address=X.X.X.X log=no log-prefix=""
chain=forward action=drop src-address=X.X.X.X log=no log-prefix=""
Replace "src-address" with your Local IP range & "dst-address" for websites or remote host you want to connect.
Hope this resolves your query.
