[Enhancement] Gufw/ufw could be linked to iptables-persistent or include extensions

[jean-christophe manciot]

Hello,

I've just installed iptables-persistent package so that my user-defined iptables rules are reloaded at each reboot.

Some rules cannot be defined with Gufw/ufw, such as for instance "sudo iptables -I OUTPUT -m geoip --dst-cc <country-code> -j ACCEPT" which uses Xtables-addons.
In order to have these manually defined iptables rules reloaded at each reboot, the correct way is to save them in 2 user-defined files such as /etc/iptables/rules.v4 & /etc/iptables/rules.v6 with "sudo iptables-save > /etc/iptables/rules.v4" & "sudo ip6tables-save > /etc/iptables/rules.v6", which will be later used by iptables-persistent at each Linux startup.
However, any change done in Gufw is subsequently lost unless a manual call to save all the rules is made each time.

So I propose 2 options to enhance Gufw:
* include in Gufw settings the possibility to define the path to iptables-persistent configuration, so that each time the user changes a rule in Gufw, it is saved there, otherwise it will be lost,
* or enhance Gufw with the possibility to use extensions such as Xtables-addons, which would prevent us from having to manipulate the iptables & install iptables-persistent package.

Your call...

Hi,

The correct way to do this would be to add your custom rules into ufw's before.rules and/or after.rules files. See https://wiki.ubuntu.com/UncomplicatedFirewall#Advanced_Functionality for more information.

Sorry, but Gufw is for normal users. Use of iptables-persistent is avanced.
About handons, as sudo app, I'll not allow that.
Thanks for the feedback.
