NAME

       rfc1918 - Shorewall file

SYNOPSIS

       /usr/share/shorewall/rfc1918

DESCRIPTION

       The rfc1918 file determines the handling of connections under the
       norfc1918 option in shorewall-interfaces[1](5). Do not modify
       /usr/share/shorewall/rfc1918; if you need to change norfc1918 handling,
       then copy /usr/share/shorewall/rfc1918 to /etc/shorewall/rfc1918 and
       modify the copy.

       The released version of this file logs and drops packets from the three
       address ranges reserved by RFC 1918:

           10.0.0.0/8
           172.16.0.0/12
           192.168.0.0/16

       The columns in the file are as follows.

       SUBNET - address
           Subnet address in CIDR format.

       TARGET - {RETURN|DROP|logdrop}
           RETURN causes packets to/from the specified subnet to be processed
           normally by the applicable rules and policies.

           DROP causes packets from the specified subnet to be silently
           dropped.

           logdrop causes packets from the specified subnet to be logged at
           the level specified by the RFC1918_LOG_LEVEL option in
           shorewall.conf[2](5).

       Also, please see the RFC1918_STRICT option in shorewall.conf[2](5).
