/ip fi la add name="UA-IDM" regexp="get /.*(user-agent: mozilla/4.0|range: bytes=)"
/ip f m add action=add-dst-to-address-list address-list=pb address-list-timeout=10m chain=forward disabled=no dst-port=39120,39100,39110,39220,49100,39190 protocol=tcp
/ip f m add action=add-dst-to-address-list address-list=pb address-list-timeout=10m chain=forward disabled=no dst-port=40000-40010 protocol=udp
/ip f f add action=accept chain=forward comment="Drop IDM" disabled=no dst-address-list=!pb layer7-protocol=UA-IDM
