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  〈shorewall-interfaces.html〉
       (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 〈shorewall.conf.html〉 (5).

       Also,  please  see  the   RFC1918_STRICT   option   in   shorewall.conf
       〈shorewall.conf.html〉 (5).
