I have problem setting permanent iptables on Debian 6 Squeeze.
I am working on a brand new instance of a server, freshly created, updated and upgraded to latest version.
Here is the tutorial I followed multiple times:
http://wiki.debian.org/iptables
I am doing all operations as root user.
After completing all the steps in the tutorial and rebooting server, the iptables are reset to default state ie. allow everything in and out.
My aim is to set them "for good", so they won't reset every time the system reboots.
I would appreciate any kind of help.
Thanks.
apt-get install iptables-persistent
and followed the steps in the wiki (no, I did not use any scripts). Is there any additional configuration involved in iptables-persistent?
