Mikrotik, Limit Download Dengan Layer 7

Limit Download Dengan Layer 7

Pusing dengan user yang download file dengan kapasitas besar sehingga mengganggu kenyamanan browsing, berikut cara untuk membatasi download dengan Layer 7 :

1. Masukkan ekstensi file di Layer 7 agar tertangkap oleh router ketika melewatinya

/ip firewall layer7-protocol add comment="" name="Extension \" .exe \"" regexp="\\.(exe)" add comment="" name="Extension \" .rar \"" regexp="\\.(rar)" add comment="" name="Extension \" .zip \"" regexp="\\.(zip)" add comment="" name="Extension \" .7z \"" regexp="\\.(7z)" add comment="" name="Extension \" .cab \"" regexp="\\.(cab)" add comment="" name="Extension \" .asf \"" regexp="\\.(asf)" add comment="" name="Extension \" .mov \"" regexp="\\.(mov)" add comment="" name="Extension \" .wmv \"" regexp="\\.(wmv)" add comment="" name="Extension \" .mpg \"" regexp="\\.(mpg)" add comment="" name="Extension \" .mpeg \"" regexp="\\.(mpeg)" add comment="" name="Extension \" .mkv \"" regexp="\\.(mkv)" add comment="" name="Extension \" .avi \"" regexp="\\.(avi)" add comment="" name="Extension \" .flv \"" regexp="\\.(flv)" add comment="" name="Extension \" .pdf \"" regexp="\\.(pdf)" add comment="" name="Extension \" .wav \"" regexp="\\.(wav)" add comment="" name="Extension \" .rm \"" regexp="\\.(rm)" add comment="" name="Extension \" .mp3 \"" regexp="\\.(mp3)" add comment="" name="Extension \" .mp4 \"" regexp="\\.(mp4)" add comment="" name="Extension \" .ram \"" regexp="\\.(ram)" add comment="" name="Extension \" .rmvb \"" regexp="\\.(rmvb)" add comment="" name="Extension \" .dat \"" regexp="\\.(dat)" add comment="" name="Extension \" .daa \"" regexp="\\.(daa)" add comment="" name="Extension \" .iso \"" regexp="\\.(iso)" add comment="" name="Extension \" .nrg \"" regexp="\\.(nrg)" add comment="" name="Extension \" .bin \"" regexp="\\.(bin)" add comment="" name="Extension \" .vcd \"" regexp="\\.(vcd)" add comment="" name="Extension \" .mp2 \"" regexp="\\.(mp2)" add comment="" name="Extension \" .3gp \"" regexp="\\.(3gp)" add comment="" name="Extension \" .mpe \"" regexp="\\.(mpe)" add comment="" name="Extension \" .qt \"" regexp="\\.(qt)" add comment="" name="Extension \" .raw \"" regexp="\\.(raw)" add comment="" name="Extension \" .wma \"" regexp="\\.(wma)" add comment="" name="Extension \" .ogg \"" regexp="\\.(ogg)" add comment="" name="Extension \" .doc \"" regexp="\\.(doc)"

2. Set IP jaringan di Address List pada Firewall

/ip firewall address-list add address=1.1.1.1 comment="" disabled=no list=bypass add address=2.2.2.2 comment="" disabled=no list=bypass add address=2.2.2.2 comment="" disabled=no list=skip_content_download add address=3.3.0.0/24 comment="" disabled=no list=skip_content_download

1.1.1.1 = ip public
2.2.2.2 = ip mikrotik / ip webproxy (jika menggunakan webproxy external berarti harus   ditambahkan ipnya di list ” bypass ”
3.3.0.0/24 = range ip jaringan lokal
Jangan lupa untuk memasukkan IP Public, IP Mikrotik atau IP Webproxy ke dalam list ” bypass ”

3. Pasang Filter di Firewall untuk menjaring ekstensi yang sedang didownload yang melalui Router Mikrotik

/ip firewall filter add action=add-dst-to-address-list address-list=content_download address-list-timeout=5s chain=forward comment="" disabled=no dst-address-list=\ !skip_content_download layer7-protocol="Extension \" .mp3 \"" protocol=tcp add action=add-dst-to-address-list address-list=content_download address-list-timeout=5s chain=forward comment="" disabled=no dst-address-list=\

5. Set PCQ dan Queue

/queue type add kind=pcq name=pcq-down pcq-classifier=dst-address pcq-limit=50 pcq-rate=256000 pcq-total-limit=2000 add kind=pcq name=Pcq_Browsing_Down pcq-classifier=dst-address pcq-li /queue tree add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 max-limit=0 name=DOWN parent=LOCAL priority=8 add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 max-limit=0 name=Browsing_Down packet-mark=Paket_Browsing parent=DOWN priority=5 \ queue=Pcq_Browsing_Down add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no max-limit=256k name=Regular_Down packet-mark=Paket_Download parent=DOWN \ priority=8 queue=pcq-down

Kalau aku sendiri cukup menggunakan Simple Queue dengan masing2 Connection Mark adalah ” Paket_Browsing ” dan ” Paket_Download ” dan terbukti ampuh juga.
Sampai disini langkah untuk membatasi Download sudah selesai …… silahkan cek paket2 yang melalui mangle apakah sudah berjalan.
Sebagai tambahan, seandainya cukup terganggu dengan pengguna IDM … bisa memasukkan perintah berikut pada Firewall

/ip firewall filter add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .exe \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .3gp \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .7z \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .asf \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .avi \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .bin \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .cab \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .daa \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .dat \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .doc \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .flv \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .iso \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .mkv \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .mov \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .mp2 \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .mp3 \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .mp4 \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .mpe \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .mpeg \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .mpg \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .nrg \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .ogg \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .pdf \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .qt \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .ram \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .rar \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .raw \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .rm \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .rmvb \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .vcd \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .wav \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .wma \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .wmv \"" protocol=tcp add action=drop chain=forward comment="" connection-limit=4,32 disabled=no in-interface=LOCAL layer7-protocol="Extension \" .zip \"" protocol=tcp
