Persistent firewall in Ubuntu

From Notes_Wiki

Home > Ubuntu > Server or Desktop administration > Persistent firewall in Ubuntu

Use of normal iptables command in Ubuntu would cause firewall rules to not persist after reboot. For persistent firewall rules in Ubuntu use:

  1. sudo apt-get update
  2. sudo apt-get install iptables-persistent
  3. Then to save current firewall rules to persist after reboot use:
    sudo invoke-rc.d iptables-persistent save
    The persistent files are saved in /etc/iptables/rules.v4 and /etc/iptables/rules.v6
