How to save and reload iptables permanently in openSUSE? [closed]

Question

I was trying to save iptable configuration and someone suggested me iptables-save which wasn't convencing for me. I logged in and tried /etc/init.d/iptables save and service command, none worked and didn't find any online reference.

-bash-4.2# iptables --version   
iptables v1.4.19.1
-bash-4.2# 

 -bash-4.2# uname  -a
Linux server 2.6.32-042stab120.6 #1 SMP Thu Oct 27 16:59:03 MSK 2016 x86_64 x86_64 x86_64 GNU/Linux
-bash-4.2#

-bash-4.2# cat /etc/SuSE-brand 
BasedOnopenSUSE
VERSION = 13.1
-bash-4.2# 

EDIT: Error message I am getting when tried /etc/init.d/iptables save and service iptables save

 server:~ # /etc/init.d/iptables save; cat /etc/os-release | grep VER
    -bash: /etc/init.d/iptables: No such file or directory
    VERSION="13.1 (Bottle)"
    VERSION_ID="13.1"
server:~ # service iptables save
service: no such service iptables

What is the command in suse to reload iptables configuration in openSUSE?

Answer 1

in openSUSE the iptables are not designed to be manipulated directly. There is no way to store the current state in a way you can reload it later.

The firewall settings are stored in /etc/sysconfig/SuSEfirewall2. You can either edit this file directly or use YaST to configure it. After changing the file you have to run /sbin/SuSEfirewall2 or service SuSEfirewall2 start to load the changes.

See the documentation for details on the configuration:

• https://en.opensuse.org/SuSEfirewall2
• /usr/share/doc/packages/SuSEfirewall2/

Answer 2

I don't know about SuSE but on CentOS the service iptables save command uses iptables-save to (eventually) write the filrewall state to /etc/sysconfig/iptables. You may want to load the script into your favourite text editor - it's generally quite readable.

When you run service iptables start, firewall stare is loaded from /etc/sysconfig/iptables.

If you want to reload the firewall state then try service iptables reload or even service iptables restart
