Konfigurasi IP Address, Gateway, DNS, NAT di Mikrotik

Setelah instalasi Mikrotik selesai selanjutnya melakukan konfigurasi IP Address, Gateway, DNS, NAT agar Mikrotik bisa terhubung ke internet. Tool yang digunakan untuk konfigurasi menggunakan Winbox.

Jalankan Winbox
Klik tombol ‘…’
Karena IP Address belum diset maka yang tampil adalah MAC Address
Winbox akan mendeteksi semua Mikrotik yang terhubung dalam jaringan

Konfigurasi bisa menggunakan GUI atau menggunakan CLI
Kali ini cukup menggunakan CLI saja
Klik New Terminal untuk menampilkan window terminal

Mengganti Nama Hostname
Defaultnya [admin@MikroTik] diganti menjadi [admin@mikrotik-lab]

system identity set name=mikrotik-lab

1	system identity set name=mikrotik-lab

Username dan Password Admin

user print Flags: X - disabled # NAME GROUP ADDRESS 0 ;;; system default user admin full

1 2 3 4 5

user print Flags: X - disabled #   NAME                        GROUP   ADDRESS 0   ;;; system default user       admin                       full

Set password = admin untuk username = admin

user set numbers=0 password=admin

1	user set numbers=0 password=admin

Set DNS Server

ip dns set servers=192.168.1.1 allow-remote-requests=yes

1	ip dns set servers=192.168.1.1 allow-remote-requests=yes

Tampilkan DNS Server

ip dns print servers: 192.168.1.1 dynamic-servers: allow-remote-requests: yes max-udp-packet-size: 4096 cache-size: 2048KiB cache-max-ttl: 1w cache-used: 29KiB

ip dns print                 servers: 192.168.1.1         dynamic-servers:   allow-remote-requests: yes     max-udp-packet-size: 4096              cache-size: 2048KiB           cache-max-ttl: 1w              cache-used: 29KiB

Tes konfigurasi dengan ping IP modem dan google.com

ping 192.168.1.1 ping google.com

1 2	ping 192.168.1.1 ping google.com

NAT (Network Address Translation)
NAT untuk mentranslasi IP Private ke IP Public atau sebaliknya.
Masksud konfigurasi dibawah ini, jika ada user yang mau terkoneksi ke internet maka paketnya dilewatkan melalui interface Ether1.

ip firewall nat add chain=srcnat out-interface=ether1 action=masquerade

1	ip firewall nat add chain=srcnat out-interface=ether1 action=masquerade

Sekarang set IP komputer client
IP Address : 192.168.10.2
Netmask : 255.255.255.0
Gateway : 192.168.10.1
DNS : 192.168.10.1
Pengujian konfigurasi client apakah terkoneksi ke mikrotik dan internet

ping 192.168.10.1 ping 192.168.1.1 ping google.com

1 2 3

ping 192.168.10.1 ping 192.168.1.1 ping google.com

Jika ping berhasil coba lakukan browsing internet.
selamat mencoba
