Konfigurasi Router Debian Lenny

Setelah berhasil menginstall debian lenny 5.04. Selanjutnya kita akan mengkonfigurasi Router. Silahkan ikuti langkah berikut :

* Kata2 yang bercetak tebal adalah perintah yang dijalankan pada komputer server.

1) nano  /etc/network/interfaces

# The primary network interface

allow-hotplug eth0

iface eth0 inet static

address 192.168.1.1

netmask 255.255.255.192

network 192.168.1.0

broadcast 192.168.1.63

gateway 192.168.1.62

# dns-* options are implemented by the resolvconf package, if installed

dns-nameservers 192.168.1.62

dns-search situstkj.co.cc

                  # The secondary network interface
                  auto eth1
                  iface eth1 inet static
                  address                   172.16.1.62
                  netmask                   255.255.255.192
                  network                   72.16.1.0
                  broadcast                172.16.1.63

2) /etc/init.d/networking  restart

3) nano /etc/sysctl.conf

# Uncomment the next line to enable packet forwarding for IPv4

net.ipv4.ip_forward=1

4) iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE5) iptables -t nat -n –L Chain PREROUTING (policy ACCEPT)

target prot opt source destination

 

Chain POSTROUTING (policy ACCEPT)

target prot opt source destination

MASQUERADE all — 0.0.0.0/0 0.0.0.0/0

 

Chain OUTPUT (policy ACCEPT)

target prot opt source destination

6) iptables-save  >  /etc/network/iptables.conf

7) echo “iptables-restore  <  /etc/network/iptables.conf”  >>  /etc/network/if-up.d/iptables”

8) nano /etc/network/if-up.d/iptables

#!/bin/sh

iptables-restore < /etc/network/iptables.conf

9) chmod  +x  /etc/network/if-up.d/iptables

10) reboot

11) ifconfig | less

12) iptables -t nat -n –L

Chain PREROUTING (policy ACCEPT)

target prot opt source destination

Chain POSTROUTING (policy ACCEPT)

target prot opt source destination

MASQUERADE all — 0.0.0.0/0 0.0.0.0/0

Chain OUTPUT (policy ACCEPT)

target prot opt source destination

(Jika terdapat kata Masquerade all berarti konfigurasi Anda Sudah Berhasil)

13) Kita check koneksinya. Pada windows ubah Settingan TCP/IP Menjadi Seperti ini:

                 IP Address                   : 172.16.1.2

                 Subnet Mask                : 255.255.255.192

                 Default Gateway           : 172.16.1.62

                 Preferred DNS Server  : 172.16.1.62

14) Setelah settingan diubah, Bukalah Command Prompt computer client dan cek koneksi ke server.
