I am using three isp providers over load balancing using \ip firewall mangle. Everything is working fine with some restrictions about accesing some website like bnt.ro
I do not understand what is wrong. The mentioned website is working fine from outside netwtork.
Please post your PCC configuration. /ip mangle export compact
If you’re using address and ports as the classifier, it will break HTTPS which doesn’t like having sessions coming in from multiple IP addresses, which will happen since the browser will open multiple connections to the server, each with it’s own source port.
