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/
Code: iptables-save > /etc/iptables-rules Edit /etc/network/interfaces under your main interface add Code: pre-up /sbin/iptables-restore < /etc/iptables-rules
Thanks first I type this command step by step Code: iptables --flush Code: iptables --table nat --flush Code: iptables --delete-chain Code: iptables --table nat --delete-chain Code: iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE Code: iptables --append FORWARD --in-interface eth1 -j ACCEPT Code: echo 1 > /proc/sys/net/ipv4/ip_forward after that I run this command Code: iptables-save > /etc/iptables-rules and then I put this line Code: pre-up /sbin/iptables-restore < /etc/iptables-rules in Code: /etc/network/interfaces before Code: auto eth0 and after description of eth0 , but after that I can not ssh to system and NAT does not work
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 Code: cat /etc/iptables-rules
