I hav a gateway runnig on SUSE 10.2 uses IPTABLES for firewall.

problem:
Evrytime i reboot machine i have to write commands of Iptables. Is there anyway by wich i can store these table forever in system.

With thanks,

You can either put the commands into a file...
text file:

Code:

#!/bin/bash
iptables -I input blah 
blah blah

Make sure the file has execute permissions and then put into /etc/init.d/filename

then chkconfig on filename
this method makes it easier to change and set iptable entries how you want them
DONE

OR

i beleive you can do iptables-save > /path/filename or something similar and it saves the current ip tables config to a file which then

then i beleive restore is possible by doing
iptables-restore < /path/filename

and then get that command to run on boot by entering it into the network set-up file or /etc/rc.d/rc.local

or something similar, rc.local method is better if you can't find it run a
find /etc/* -name 'rc.local'

hope this helps

I think after you load all rules:
/sbin/iptables-save >iptables.save
The next time you boot:
/sbin/iptables-restore <iptables.save
If you change any rules you have to do a iptables-save again.
