Hello,
I have found that many users in our network are using sites like “www.filterbypass.me” **[**a free anonymous web proxy] to bypass firewall rules. There are lots of such sites where user can bypass our firewall rules and access the sites.
Is there anyway to stop?
set up your own proxy in the mikrotik device, and force redirect all web traffic to yours. block all other traffic. this will only work for HTTP traffic, HTTPS will not work.
you can also intercept DNS requests and redirect to some DNS server where you can set up filters
