    Ane cuman bisa drop udp nya dengan cara begini,
    Code:
    /ip address firewall filter add chain=output action=drop protocol=udp src-address=202.xxx.xxx.xxx dst-port=!53 
    Mungkin ada yang punya cara lain? di karenakan Flooding di IP src dynamic, port pun blank.

    yg bermasalah flood upload WAN, padahal di sisi LAN ga ada trafik aneh
    coba kontak ke teknisi ISP,saat network lokal OFF semua awasi trafik yg ada

    coba buat firewall yg mengizinkan state=new.
    selebihnya drop. (hati-hati dengan rule drop). dan jangan lupa allow established connection dan related connection.
