## Name

params — Shorewall parameters file

## Synopsis

`/etc/shorewall[6]/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 shorewall.conf (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 shorewall.conf (5)
COMMAND
CONFDIR
DEBUG
ECHO_E
ECHO_N

Example params file:

    NET_IF=eth0
    NET_BCAST=130.252.100.255
    NET_OPTIONS=routefilter

Example shorewall-interfaces(5) file.

    ZONE    INTERFACE       BROADCAST       OPTIONS
    net     $NET_IF         $NET_BCAST      $NET_OPTIONS

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

    ZONE    INTERFACE       BROADCAST       OPTIONS
    net     eth0            130.252.100.255 routefilter
