ubuntu 10.04에는 ipmasq 패키지가 없넹? 다음과 같이 ufw를 사용해 maquerading 을 할 수 있음.

/etc/default/ufw
<code>
DEFAULT_FORWARD_POLICY="ACCEPT"
</code>

/etc/ufw/sysctl.conf
<code>
net.ipv4.ip_forward=1
</code>

/etc/ufw/before.rules
<code>
# nat Table rules
*nat
:POSTROUTING ACCEPT [0:0]

# Forward traffic from eth1 through eth0.
-A POSTROUTING -s 192.168.0.0/24 -o eth0 -j MASQUERADE

# don't delete the 'COMMIT' line or these nat table rules won't be processed
COMMIT
</code>

다음 명령으로 ufw 재 시작
<code bash>
sudo ufw disable && sudo ufw enable
</code>
