# 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 in the 'rfc1918' 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.
