# Shorewall version 1.2 - Rules File

#
|
|
# /etc/shorewall/rules
|
|
#
|
|
# Rules in this file govern connection establishment. Requests and
|
|
# responses are automatically allowed using connection tracking.
|
|
#
|
|
# Columns are:
|
|
#
|
|
#
|
|
# RESULT ACCEPT, DROP or REJECT
|
|
#
|
|
# ACCEPT -- allow the connection request
|
|
# DROP -- ignore the request
|
|
# REJECT -- disallow the request and return an
|
|
# icmp-unreachable packet.
|
|
#
|
|
# The line may NOT start with $<variable-name>
|
|
#
|
|
# May optionally be followed by ":" and a syslog log
|
|
# level (e.g, REJECT:info). This causes the packet to be
|
|
# logged at the specified level.
|
|
#
|
|
# CLIENT(S) Hosts permitted to be clients. May be a zone defined
|
|
# in /etc/shorewall/zones or "fw" to indicate the
|
|
# firewall itself.
|
|
#
|
|
# Clients may be further restricted to a particular
|
|
# subnet or host by appending ":" and the subnet or host.
|
|
#
|
|
# dmz:192.168.2.2 Host 192.168.2.2 in the DMZ
|
|
# net:155.186.235.0/24 Subnet 155.186.235.0/24 on the
|
|
# Internet
|
|
#
|
|
# Alternatively, clients may be specified by interface
|
|
# by appending ":" followed by the interface name. For
|
|
# example, loc:eth1 specifies a client that
|
|
# communicates with the firewall system through eth1.
|
|
#
|
|
# SERVER Location of Server. May be a zone defined in
|
|
# /etc/shorewall/zones or "fw" to indicate the firewall
|
|
# itself.
|
|
#
|
|
# The server may be further restricted to a particular
|
|
# subnet, host or interface by appending ":" and the
|
|
# subnet, host or interface. See above.
|
|
#
|
|
# The port that the server is listening on may be
|
|
# included and separated from the server's IP address by
|
|
# ":". If omitted, the firewall will not modifiy the
|
|
# destination port.
|
|
#
|
|
# Example: loc:192.168.1.3:8080 specifies a local
|
|
# server at IP address 192.168.1.3 and listening on port
|
|
# 8080. The port number MUST be specified as an integer
|
|
# and not as a name from /etc/services.
|
|
#
|
|
# PROTO Protocol - Must be "tcp", "udp", "icmp", a number,
|
|
# "all" or "related". If "related", the remainder of the
|
|
# entry must be omitted and connection requests that are
|
|
# related to existing requests will be accepted.
|
|
#
|
|
# PORT(S) Destination Port. A comma-separated list of Port names
|
|
# (from /etc/services), port numbers or port ranges;
|
|
# if the protocol is "icmp", this column is interpreted as
|
|
# the destination icmp-type. If this column contains the
|
|
# value "none", the rule is ignored.
|
|
#
|
|
# This column is ignored if PROTOCOL = all but must be
|
|
# entered if any of the following fields are supplied.
|
|
# In that case, it is suggested that this field contain
|
|
# "-"
|
|
#
|
|
# CLIENT PORT(S) (Optional) Port(s) used by the client. If omitted,
|
|
# any source port is acceptable.
|
|
#
|
|
# If you don't want to restrict client ports but need to
|
|
# specify an ADDRESS in the next column, then place "-"
|
|
# in this column.
|
|
#
|
|
# ADDRESS (0ptional) If included and different from the IP
|
|
# address given in the SERVER column, this is an address
|
|
# on some interface on the firewall and connections to
|
|
# that address will be forwarded to the IP and port
|
|
# specified in the SERVER column.
|
|
#
|
|
# If the special value "all" is used, then requests from
|
|
# the client zone given in the CLIENT(s) column with the
|
|
# destination port given in PORT(s) will be forwarded to
|
|
# the IP address given in SERVER.
|
|
#
|
|
# The address (or "all") may optionally be followed by
|
|
# a colon (":") an an IP address. This causes Shorewall
|
|
# to use the specified IP address as the source address
|
|
# in forwarded packets. See the Shorewall documentation
|
|
# for restrictions concerning this feature. If no source
|
|
# IP address is given, the original source address is not
|
|
# altered.
|
|
#
|
|
# Example: Forward all ssh and www connection requests from the internet to
|
|
# local system 192.168.1.3
|
|
#
|
|
# #RESULT CLIENTS SERVER(S) PROTO PORT(S) CLIENT PORT(S) ADDRESS
|
|
# ACCEPT net loc:192.168.1.3 tcp ssh,www - all
|
|
#
|
|
# Example: Redirect all locally-originating www connection requests to
|
|
# port 8080 on the firewall (Squid running on the firewall
|
|
# system)
|
|
#
|
|
# #RESULT CLIENTS SERVER(S) PROTO PORTS(S) CLIENT PORT(S) ADDRESS
