    @george1421 there is a DHCP section in the post. I will include DNS as well. Right now I wish to keep those options separate. Eventually the installer should automatically configure the firewall based on installation preference.

    Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

      Sorry I missed that. I copied the top sections and skipped the bottom.

        the firewalld stuff works fine on Fedora 23 Server so far.

        I’ve tried this setup on a virtualized Fedora 23 DHCP server, and a virtualized Fedora 23 FOG server (using only the settings each one needs). I’ve imaged 2 computers so far with this setup. One of them, I tried out WOL just to confirm that still works - it does.

          For the record - I’ll be using the Firewalld configuration at work soon - I’ll be doing it safely though. I’m keeping my old virtual FOG server in-tact but shutdown, and I’m setting up a new one on Fedora 23 using this configuration.

          I’m really confident that the Firewalld settings will work really well - They’ve worked fine at home so far for me.

          I’m holding off on adding this stuff to the WiKi because I feel it will be integrated into the installer prior to 1.3.0 being released @Developers. 🙂

          I’m not so confident about the iptables config - but I haven’t used it. The only thing that concerns me is the NFS ports. 😕 Hopefully some Ubuntu and Debian users can try it out soon and let us know how it works? @ch3i

            I’ve been running the firewalld settings in production with Fedora 23 and I’m cautiously optimistic.

              @Developers I have successfully operated at work for about two weeks now with the Firewalld portion of these instructions active. In my opinion, the firewalld stuff should be implimented into the installer for further testing.

              A good question is how to impliment them. Should the installer “just do it” or should it be a installation argument?

              If the argument route was taken, it could be something as simple as:

              ./installfog.sh --firewall yes

              or

              ./installfog.sh --firewall no

              With the option stored in /opt/fog/.fogsettings with the default being yes

                  I’m using ufw in a debian 8 system with:

                  ufw default deny incoming
                  ufw default allow outgoing

                  #ports 21ftp, 22ssh, 80web, 111rpc, 69tftp, 443web, 2049nfs, 20499-nfs
                  ufw allow from 192.168.0.0/24 to any port 21,22,80,111,443,2049,20499 proto tcp
                  ufw allow from 192.168.0.0/24 to any port 69,111,2049,6080 proto udp
                  ufw enable

                  I changed nfs to work with the firewall on debian
                  #from
                  RPCMOUNTDOPTS=“–manage-gids”
                  #to
                  RPCMOUNTDOPTS=“-p 20499”
                  #and
                  systemctl restart nfs-kernel-server.service

                          It lacked a row before ufw enable:

                          ufw allow from 192.168.0.255

                          to fit our net environment

                            the firewalld configuration no longer works on Fedora 21.

                            The commands succeed, but at least http is blocked still.
