Konfigurasi Router Debian 7

Terlebih dahulu setting IP masing-masing interfaces:

~# nano /etc/network/interfaces

auto lo eth0 eth1

iface lo inet loopback

iface eth0 inet static

address 192.168.1.15

netmask 255.255.255.0

network 192.168.1.0

broadcast 192.168.1.254

gateway 192.168.1.1

iface eth1 inet static

address 172.10.15.1

netmask 255.255.255.224

network 172.10.15.0

broadcast 172.10.15.32

setelah itu disimpan (CTRL+O <enter>, CTRL+X)

~# apt-get install iptables

~# nano /etc/sysctl.conf

cari teks berikut

#net.ipv4.ip_forward=1

Lalu lepas tanda pagar (#) untuk diaktifkan:

net.ipv4.ip_forward=1

setelah itu disimpan (CTRL+O <enter>, CTRL+X)

~# nano /etc/rc.local

Masukkan perintah berikut di atas teks “Exit 0”

echo 1 > /proc/sys/net/ipv4/ip_forward

iptables –t nat –A POSTROUTING –o eth0 –j MASQUERADE

exit 0

setelah itu disimpan (CTRL+O <enter>, CTRL+X)

~# service networking restart
