IPTable Rules and Rebooting for Debian / Ubuntu
IPTable Rules and Rebooting for Debian / Ubuntu
By drendeah
The other day I wrote an article on Setting up IPTables for a Simple Linux Web Server. In that article I mentioned that after you make the desired changes to your IPTable rules you must save the changes in order for the rules to persist a reboot of the server. I also mentioned that under Debian and Ubuntu there is not an automated command for saving and restoring the IPTable rules.
Code:
# iptables -save
# iptables -restoreThe above two commands save and restore the IPTable rules under some Linux distros, but not Debian and Ubuntu.
