-====== IPTables - Save IPTable rules ======
-===== Save the iptables rules =====
-The generic method of saving iptables rules is to use the command **iptables-save**, which writes to stdout.
-<code bash>
-iptables-save > /etc/network/iptables.rules
-</code>
-===== Restore the iptables rules =====
-The output created by **iptables-save** can then by read on stdin by **iptables-restore**.
-If on a server, without NetworkManager, a common approach is then to use a **pre-up** command in /etc/network/interfaces.
-<file /etc/network/interfaces>
-iface eth0 inet static
-        ....
-        pre-up iptables-restore < /etc/network/iptables.rules
-</file>
-**NOTE**:  Do note that the commands iptables, **iptables-save** and **iptables-restore** are IPv4 only. For IPv6 traffic the equivalent commands are ip6tables, **ip6tables-save** and **ip6tables-restore**.
