Thread: SUSE 12.3 basic firewall set up

    Default SUSE 12.3 basic firewall set up

    Hi, My knowledge of firewalls is limited to previously installing commercial ones on my PC using windows. They don't appear to require much in the way of user input. I know SUSE has a firewall but what should I do on a fresh install to ensure that the system has adequate protection for accessing the internet?
    I have used YAST to start the firewall automatically at start up, but I've done little else. Under headings such as allowed services masquerading broadcast etc there are no entry’s. Using the security centre and hardening link in Yast I have selected the predefined security configuration of Networked Workstation.
    Are these settings enough for a machine using the internet? Or do I need to go into more depth and configure things more fully? Any advice would be welcome.

    Regards Steve Jarvis

    Run the installer and install openSUSE. Seriously - that's all you need
    to do with a default installation. The firewall is an ingres firewall,
    and by default everything is closed (unless you tell the installer to
    open a port, for example, for ssh).

    You can modify the configuration using YaST - there's a firewall module.

    Nothing.

    The default firewall protects you, and you only need to change it IF you
    are offering services to others.
