What do you want to achive ? If a cable from your isp router is connected into ether1 interface and ether1 has been assigned ip address 192.168.0.15 (/24 i suppose), in ether 2 what is connected? is there a cable who is then connected into a switch in which are connected both your servers or your servers are connected directly into ether 2, ether 3 ports on mikrotik router? What is your network topology?
