1) 아래를 터미널에서 입력한다.


# echo "1"> /proc/sys/net/ipv4/ip_forward
# iptables -P FORWARD DROP
# iptables -A FORWARD -o eth0 -j ACCEPT
# iptables -A FORWARD -o eth1 -j ACCEPT
# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
# ifconfig eth1 192.168.0.1 up

2) 이때 ethernet setting을 위해 다음을 입력하여  interfaces를 연다.

# sudo gedit /etc/network/interfaces

3) interfaces에 다음 내용을 입력.

#===============================

#The loopback network interface

auto lo

iface lo inet loopback

#The primary network interface

auto eth0

iface eth0 inet static

address xxx.xxx.xxx.xxx

netmask 255.255.255.0

gateway xxx.xxx.xxx.xxx

dns-nameservers xxx.xxx.xxx.xxx,xxx.xxx.xxx.xxx

 

#The secondary network interface for ipforwarding

#auto eth1

iface eth1 inet static

address 192.168.0.1

netmask 255.255.255.0

#iface eth1 inet dhcp

#=================================


4) 이 후 네트워크를 재시작...


# /etc/init.d/networking restart
