Cara Konfigurasi IP Address, DNS Client dan NAT di Ubuntu Server

Setting ip interface

sudo nano /etc/network/interfaces

1	sudo nano /etc/network/interfaces

Default konfigurasi eth0 menggunakan IP DHCP :

auto eth0
iface eth0 inet dhcp

1 2	auto eth0 iface eth0 inet dhcp

Rubah menjadi :

auto eth0
iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 8.8.8.8 8.8.4.4 #Setting DNS Client Ubuntu 12.04

auto eth0

iface eth0 inet static

address 192.168.1.10

netmask 255.255.255.0

gateway 192.168.1.1

dns-nameservers 8.8.8.8 8.8.4.4 #Setting DNS Client Ubuntu 12.04

auto eth1
iface eth1 inet static
address 10.10.10.1
netmask 255.255.255.0

auto eth1

iface eth1 inet static

address 10.10.10.1

netmask 255.255.255.0
