debian 4 and NAT

[mfaridi]

I use this link for configure NAT on Debian 4 and do everything this link said

http://www.howtoforge.org/nat_iptables

but after reboot system I have to do all of this command for run
how I can save this rules and use them in reboot ???

How I can make script from rule and put them in /init.d/

[topdog]

iptables-save > /etc/iptables-rules

Edit /etc/network/interfaces under your main interface add

pre-up /sbin/iptables-restore < /etc/iptables-rules

Thanks
first I type this command step by step

iptables --flush

iptables --table nat --flush

iptables --delete-chain

iptables --table nat --delete-chain

iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE

iptables --append FORWARD --in-interface eth1 -j ACCEPT

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

after that I run this command

iptables-save > /etc/iptables-rules

and then I put this line

pre-up /sbin/iptables-restore < /etc/iptables-rules

in

/etc/network/interfaces

before

auto eth0

and after description of eth0 , but after that I can not ssh to system and NAT does not work

[topdog]

That goes under iface eth0 ....
Note that the rules provided there are just for NAT no firewalling rules are entered.

what is the output of the file ? To see why you cannot ssh in

cat /etc/iptables-rules
