iptables-save command should be called iptables-dump…

You can’t use this command to save iptables rules.

In yunohost the prefer way to manage that usecase to create a hook by following these steps:

1. create a dir /etc/yunohost/hooks.d/post\_iptable\_rules
2. add a file in this dir called 99-specific\_rules with 🙂

```auto
#!/bin/bash
sudo iptables <YOUR SPECIFIC RULES HERE>
sudo ip6tables <YOUR SPECIFIC RULES HERE>

```
