# Shorewall 2.2 -- RFC1918 File
#
# /etc/shorewall/rfc1918
#
# Lists the subnetworks that are blocked by the 'norfc1918' interface option.
#
# The default list includes those IP addresses listed in RFC 1918.
#
# DO NOT MODIFY THIS FILE. IF YOU NEED TO MAKE CHANGES, COPY THE FILE
# TO /etc/shorewall AND MODIFY THE COPY.
#
# Columns are:
#
# SUBNETS A comma-separated list of subnet addresses
# (host addresses also allowed as are IP
# address ranges provided that your kernel and iptables
# have iprange match support).
# TARGET Where to send packets to/from this subnet
# RETURN - let the packet be processed normally
# DROP - silently drop the packet
# logdrop - log then drop
#
# By default, the RETURN target causes 'norfc1918' processing to cease for a
# packet if the packet's source IP address matches the rule. Thus, if you have:
#
# SUBNETS TARGET
# 192.168.1.0/24 RETURN
#
# then traffic from 192.168.1.4 to 10.0.3.9 will be accepted even though you
# also have:
#
# SUBNETS TARGET
# 10.0.0.0/8 logdrop
#
# Setting RFC1918_STRICT=Yes in shorewall.conf will cause such traffic to be
# logged and dropped since while the packet's source matches the RETURN rule,
# the packet's destination matches the 'logdrop' rule.
