a website or a visual basic Named (NTH-Mikrotik) that can enter a number ( X ) and (X) interface print that. Number of NHT ( 3 ) - Interface name (ether10) : ======================================== /ip firewall mangle add action=mark-connection chain=prerouting connection-state=new dst-address-type=!local in-interface=ether10 new-connection-mark=conn1 nth=3,1 passthrough=yes add action=mark-routing chain=prerouting connection-mark=conn1 in-interface=ether10 new-routing-mark=conn1 passthrough=no add action=mark-connection chain=prerouting connection-state=new dst-address-type=!local in-interface=ether10 new-connection-mark=conn2 nth=2,1 passthrough=yes add action=mark-routing chain=prerouting connection-mark=conn2 in-interface=ether10 new-routing-mark=conn2 passthrough=no add action=mark-connection chain=prerouting connection-state=new dst-address-type=!local in-interface=ether10 new-connection-mark=conn3 nth=1,1 passthrough=yes add action=mark-routing chain=prerouting connection-mark=conn3 in-interface=ether10 new-routing-mark=conn3 passthrough=no /ip route add check-gateway=ping distance=1 gateway=pppoe-out1 routing-mark=conn1 scope=255 add check-gateway=ping distance=1 gateway=pppoe-out2 routing-mark=conn2 scope=255 add check-gateway=ping distance=1 gateway=pppoe-out3 routing-mark=conn3 scope=255 add distance=1 gateway=pppoe-out1 add distance=1 gateway=pppoe-out2 add distance=1 gateway=pppoe-out3 so when i put number 2 and interface name is bridge1 the script will be this : ============================================================== /ip firewall mangle add action=mark-connection chain=prerouting connection-state=new dst-address-type=!local in-interface=bridge1 new-connection-mark=conn1 nth=2,1 passthrough=yes add action=mark-routing chain=prerouting connection-mark=conn1 in-interface=ether10 new-routing-mark=conn1 passthrough=no add action=mark-connection chain=prerouting connection-state=new dst-address-type=!local in-interface=bridge1 new-connection-mark=conn2 nth=1,1 passthrough=yes add action=mark-routing chain=prerouting connection-mark=conn2 in-interface=ether10 new-routing-mark=conn2 passthrough=no /ip route add check-gateway=ping distance=1 gateway=pppoe-out1 routing-mark=conn1 scope=255 add check-gateway=ping distance=1 gateway=pppoe-out2 routing-mark=conn2 scope=255 add distance=1 gateway=pppoe-out1 add distance=1 gateway=pppoe-out2 so the changes only on in-interface by names and the nth and ip route if adding 3 or 2 or 100...etc
