       shorewall-init - Companion package


       /etc/init.d/shorewall-init [start|stop]


       Shorewall-init is an optional package (added in Shorewall 4.4.10) that
       can be installed along with Shorewall, Shorewall6, Shorewall-lite
       and/or Shorewall6-lite. It provides two key features:

        1. It can close (stop) the firewall during boot prior to starting the
           network. This can prevent unwanted connections from being accepted
           after the network comes up but before the firewall is started.

        2. It can interface with your distribution's ifup/ifdown scripts
           and/or NetworkManager to allow firewall actions when an interface
           starts or stops.

       These two capabilities can be enabled separately.

       After you install the shorewall-init package, you can activate it by
       modifying the Shorewall-init configuration file:

       ·   On Debian-based system, the file is /etc/default/shorewall-init.

       ·   On other systems, the file is /etc/sysconfig/shorewall-init.

       To activate the safe boot feature, edit the configuration file and set
       PRODUCTS to a space-separated list of Shorewall products that you want
       to be closed before networking starts.

           PRODUCTS="shorewall shorewall6"

       You also must insure that the compiled scripts for the listed products
       are compiled using Shorewall 4.4.10 or later.

           shorewall compile

           shorewall6 compile

           On the administrative system, enter the command shorewall export
           firewall from the firewall's configuration directory.

           On the administrative system, enter the command shorewall6 export
           firewall from the firewall's configuration directory.

       The second feature (ifup/ifdown and NetworkManager integration) should
       only be activated on systems that do not use a link status monitor line
       swping or LSM.

       ·   Edit the configuration file and set IFUPDOWN=1

       For NetworkManager integration, you will want to disable firewall
       startup at boot and delay it to when your interface comes up. For this
       to work correctly, you must set the required or the optional option on
       at least one interface then:

       ·   On Debian-based systems, edit /etc/default/product for each product
           listed in the PRODUCTS setting and set startup=0.

       ·   On other systems, use the distribution's service control tool
           (insserv, chkconfig, etc.) to disable startup of the products
           listed in the PRODUCTS setting.

       On a laptop with both ethernet and wireless interfaces, you will want
       to make both interfaces optional and set the REQUIRE_INTERFACE option
       to Yes in shorewall.conf[1](5) or shorewall6.conf[2] (5). This causes
       the firewall to remain stopped until at least one of the interfaces
       comes up.
