iptables+nat

[gaspo <gaspolo@gmail.com>]

hi i have installed debian on my ultra 5...
i wanna setting up NAT connection for my 2 client window...
i make that command:
ifconfig eth0 192.168.1.1
iptables -t nat -A POSTROUTING -o hme0 -s 192.168.1.1/24 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
...
but iptables say:
debian:/etc/init.d# iptables -t nat -A POSTROUTING -o hme0 -s
192.168.1.1/24 -j MASQUERADE
iptables: No chain/target/match by that name

debian:/etc/init.d# uname -a
