Mikrotik How To

This is my firewall mangle, Nat, and Routing Rules for Load Balance with NTH metod at mikrotik 3.x. With This Rules, we can optimize if we have more than one internet connection from ISP's. For Example, if i have 3 line source internet where each speed is 1Mbps, we can optimize to be 3Mbps in one time. To Test this setting, i use Internet Download Manager. Ok this is my rules:



/ip firewall mangle
