Perintah Dasar Pada Mikrotik Router

Artikel ini saya Copy Paste dari sini

 

Deteksi kartu jaringan
interface print
rubah nama kartu jaringan
interface set ether1 name= PUBLIC

interface set ether2 name= LOCAL
interface set ether3 name= PROXY
rubah hostname
system identity set name= ROUTER

Setting dasar
system identity set name=’ROUTER’
ip address add address=10.32.100.254
ip route add gateway=10.32.200.1
ip dns set primary=202.134.0.155 scondary=202.130.193.74
ip firewall nat add shain=srcnat action=masquerade out-interface=PUBLIC

ip firewall address-list
add list=ournetwork address=10.32.200.0/24 comment=”IP Junifer Jardiknas” disabled=no
add list=ournetwork address=192.168.0.0/24 comment=”IP LAN” disabled=no
add list=ournetwork address=192.168.1.0/30 comment=”IP VLAN” disabled=no
add list=ournetwork address=172.16.8.0/24 comment=”IP ICTC” disabled=no
add list=ournetwork address=172.16.6.0/24 comment=”IP RADIOICTC” disabled=no

Setting keamanan
Buat skrtip berikut menggunakan notepad kemudian copy-paste ke console mikrotik
Selanjutnya copy-paste skrip berikut pada console mikrotik

Efek dari skrip diatas adalah:
router mikrotik hanya dapat diakses FTP, SSH, Web dan Winbox dari IP yang didefinisikan dalam address-list “ournetwork” sehingga tidak bisa diakses dari sembarang tempat.
Port-port yang sering dimanfaatkan virus di blok sehingga traffic virus tidak dapat dilewatkan, tetapi perlu diperhatikan jika ada user yang kesulitan mengakses service tertentu harus dicek pada chain=”virus” apakah port yang dibutuhkan user tersebut terblok oleh firewall.
Packet ping dibatasi untuk menghindari excess ping.

kalo ada pertanyaan langsung ke situs sumbernya aja, soale aku tidak tahu apa-apa
