shorewall6-params(5)

NAME

   params - Shorewall6 parameters file

SYNOPSIS

   /etc/shorewall6/params

DESCRIPTION

   Assign any shell variables that you need in this file. The file is
   always processed by /bin/sh or by the shell specified through
   SHOREWALL_SHELL in shorewall6.conf[1] (5) so the full range of shell
   capabilities may be used.

   It is suggested that variable names begin with an upper case letter to
   distinguish them from variables used internally within the Shorewall
   programs

   The following variable names must be avoided. Those in bold font must
   be avoided in all Shorewall versions; those in regular font must be
   avoided in versions prior to 4.4.8.
       Any option from shorewall6.conf[1]

   Example params file:

       NET_IF=eth0
       NET_OPTIONS=dhcp,nosmurfs

   Example shorewall6-interfaces[2](5) file.

       ZONE    INTERFACE       BROADCAST       OPTIONS
       net     $NET_IF         -               $NET_OPTIONS

   This is the same as if the interfaces file had contained:

       ZONE    INTERFACE       BROADCAST       OPTIONS
       net     eth0            -               dhcp,nosmurfs
