Warning:< br >
< br >
If your shell only supports 32-bit signed arithmatic (ash or dash),
then the ipcalc command produces incorrect information for IP addresses
128.0.0.0-1 and for /1 networks. Bash should produce correct information
for all valid IP addresses.< br >

This command decomposes a range of IP addressses into a list of

an efficient set of rules that accept connections from a range of network
addresses.< br >

Note: If your shell only supports 32-bit signed arithmetic (ash

Warning:< br >
< br >
If your shell only supports 32-bit signed arithmatic (ash or dash), then
the ipcalc command produces incorrect information for IP addresses 128.0.0.0-1
and for /1 networks. Bash should produce correct information for all valid
IP addresses.< br >

< br >
<20> <> <EFBFBD> <EFBFBD> <EFBFBD> iprange < address> -< address> < br >
< br >
This command decomposes a range of IP addressses into a list of network
and host addresses. The command can be useful if you need to construct an
efficient set of rules that accept connections from a range of network addresses.< br >
< br >
Note: If your shell only supports 32-bit signed arithmetic (ash or dash)
then the range may not span 128.0.0.0.< br >

Note that this capability has previously been available using a combination
of a DNAT- rule and one or more ACCEPT rules. That technique is still
preferable for load-balancing over a large number of servers (> 16)

The Fireparse --log-prefix fiasco continues. Tuomo Soini has
pointed out that the code in 1.4.4 restricts the length of short zone
names to 4 characters. I've produced version 1.4.4a that restores the
previous 5-character limit by conditionally omitting the log rule number
when the LOGFORMAT doesn't contain '%d'. < br >
< p > < b > 5/23/2003 - Shorewall-1.4.4< / b > < / p >
I apologize for the rapid-fire releases but since there is
a potential configuration change required to go from 1.4.3a to 1.4.4,
I decided to make it a full release rather than just a bug-fix release.

< li > Where an entry in the/etc/shorewall/hosts file
specifies a particular host or network, Shorewall now creates
an intermediate chain for handling input from the related zone.
This can substantially reduce the number of rules traversed by connections
requests from such zones.< br >

INCLUDE directive consists of the word INCLUDE followed by a file

< li > Routing traffic from an interface back out that
interface continues to be a problem. While I firmly believe that
this should never happen, people continue to want to do it. To limit
the damage that such nonsense produces, I have added a new 'routeback'
option in /etc/shorewall/interfaces and /etc/shorewall/hosts. When
used in /etc/shorewall/interfaces, the 'ZONE' column may not contain
'-'; in other words, 'routeback' can't be used as an option for a multi-zone
interface. The 'routeback' option CAN be specified however on individual
group entries in /etc/shorewall/hosts.< br >
<20> < br >
The 'routeback' option is similar to the old 'multi'
option with two exceptions:< br >
<20> < br >
<20> <> a) The option pertains to a particular zone,interface,address
tuple.< br >
<20> < br >
<20> <> b) The option only created infrastructure to pass
traffic from (zone,interface,address) tuples back to themselves
(the 'multi' option affected all (zone,interface,address) tuples
associated with the given 'interface').< br >
<20> < br >
See the '< a href = "upgrade_issues.htm" > Upgrade Issues< / a > '
for information about how this new option may affect your configuration.< br >

ping handling is as it has always been (see http://www.shorewall.net/ping.html).< br >
< br >
When OLD_PING_HANDLING=No, icmp
echo (ping) is handled via rules and policies just like
any other connection request. The FORWARDPING=Yes option

name:< br >

< li > In /etc/shorewall/tcrules, the MARK
value may be optionally followed by ":" and either 'F' or 'P'
to designate that the marking will occur in the FORWARD or PREROUTING
chains respectively. If this additional specification is omitted,
the chain used to mark packets will be determined by the setting
of the MARK_IN_FORWARD_CHAIN option in < a

< br >
< / li >
< li > When an interface name is entered
in the SUBNET column of the /etc/shorewall/masq file, Shorewall
previously masqueraded traffic from only the first subnet
defined on that interface. It did not masquerade traffic from:< br >
<20> < br >
<20> <> a) The subnets associated with
other addresses on the interface.< br >
<20> <> b) Subnets accessed through local
routers.< br >
<20> < br >
Beginning with Shorewall 1.3.14,
if you enter an interface name in the SUBNET column, shorewall
will use the firewall's routing table to construct the masquerading/SNAT
rules.< br >

When upgrading to Shorewall 1.3.14,
if you have multiple local subnets connected to an interface
that is specified in the SUBNET column of an /etc/shorewall/masq
entry, your /etc/shorewall/masq file will need changing. In
most cases, you will simply be able to remove redundant entries.
In some cases though, you might want to change from using the interface
name to listing specific subnetworks if the change described above
will cause masquerading to occur on subnetworks that you don't wish

to masquerade.< br >

< li > An OLD_PING_HANDLING option
has been added to shorewall.conf. When set to Yes, Shorewall
ping handling is as it has always been (see http://www.shorewall.net/ping.html).< br >
< br >
When OLD_PING_HANDLING=No, icmp
echo (ping) is handled via rules and policies just like
any other connection request. The FORWARDPING=Yes option
in shorewall.conf and the 'noping' and 'filterping' options in
/etc/shorewall/interfaces will all generate an error.< br >
< br >
< / li >
< li > It is now possible to direct
Shorewall to create a "label" such as<61> "eth0:0" for IP addresses
that it creates under ADD_IP_ALIASES=Yes and ADD_SNAT_ALIASES=Yes.
This is done by specifying the label instead of just the interface
name:< br >
<20> < br >
<20> <> a) In the INTERFACE column of
/etc/shorewall/masq< br >
<20> <> b) In the INTERFACE column of
/etc/shorewall/nat< br >
<20> < / li >
< li > When an interface name is
entered in the SUBNET column of the /etc/shorewall/masq
file, Shorewall previously masqueraded traffic from only
the first subnet defined on that interface. It did not masquerade
traffic from:< br >
<20> < br >
<20> <> a) The subnets associated with
other addresses on the interface.< br >
<20> <> b) Subnets accessed through local
routers.< br >
<20> < br >
Beginning with Shorewall 1.3.14,
if you enter an interface name in the SUBNET column, shorewall
will use the firewall's routing table to construct the masquerading/SNAT
rules.< br >
<20> < br >
Example 1 -- This is how it works
in 1.3.14.< br >

When upgrading to Shorewall 1.3.14,
if you have multiple local subnets connected to an interface
that is specified in the SUBNET column of an /etc/shorewall/masq
entry, your /etc/shorewall/masq file will need changing. In
most cases, you will simply be able to remove redundant entries.
In some cases though, you might want to change from using the interface
name to listing specific subnetworks if the change described above
will cause masquerading to occur on subnetworks that you don't wish

to masquerade.< br >

< li > A new 'DNAT-' action has
been added for entries in the /etc/shorewall/rules file.
DNAT- is intended for advanced users who wish to minimize the
number of rules that connection requests must traverse.< br >
< br >
A Shorewall DNAT rule actually
generates two iptables rules: a header rewriting rule
in the 'nat' table and an ACCEPT rule in the 'filter' table.
A DNAT- rule only generates the first of these rules. This
is handy when you have several DNAT rules that would generate the
same ACCEPT rule.< br >
< br >
<20> <> Here are three rules from
my previous rules file:< br >

< li > The 'shorewall check'
command now prints out the applicable policy between
each pair of zones.< br >
< br >
< / li >
< li > A new CLEAR_TC option
has been added to shorewall.conf. If this option is set
to 'No' then Shorewall won't clear the current traffic control
rules during [re]start. This setting is intended for use by
people that prefer to configure traffic shaping when the network
interfaces come up rather than when the firewall is started. If
that is what you want to do, set TC_ENABLED=Yes and CLEAR_TC=No
and do not supply an /etc/shorewall/tcstart file. That way, your
traffic shaping rules can still use the 'fwmark' classifier based
on packet marking defined in /etc/shorewall/tcrules.< br >
< br >
< / li >
< li > A new SHARED_DIR variable
has been added that allows distribution packagers to
easily move the shared directory (default /usr/lib/shorewall).
Users should never have a need to change the value of this
shorewall.conf setting.< br >

now turns off debugging after an error occurs. This
places the point of the failure near the end of the trace
rather than up in the middle of it.< / li >

has been speeded up by more than 40% with my configuration.

command has been added which shows the current packet
classification filters. The output from this command
is also added as a separate page in "shorewall monitor"< / li >
< li > ULOG (must be all caps)
is now accepted as a valid syslog level and causes
the subject packets to be logged using the ULOG target rather
than the LOG target. This allows you to run ulogd (available

("shorewall show mangle" will show you the chains in the
mangle table), you can set MARK_IN_FORWARD_CHAIN=Yes in

for marking input packets based on their destination even when
you are using Masquerading or SNAT.< / li >
< li > I have cluttered up
the /etc/shorewall directory with empty 'init', 'start',
'stop' and 'stopped' files. If you already have a file with
one of these names, don't worry -- the upgrade process won't
overwrite your file.< / li >
< li > I have added a new
RFC1918_LOG_LEVEL variable to < a
href="Documentation.htm#Conf">shorewall.conf< / a > . This variable
specifies the syslog level at which packets are logged
as a result of entries in the /etc/shorewall/rfc1918 file.

< li > The 'icmp.def' file is now empty! The rules
in that file were required in ipchains firewalls
but are not required in Shorewall. Users who have
ALLOWRELATED=No in < a href = "Documentation.htm#Conf" > shorewall.conf< / a >
should see the < a href = "errata.htm#Upgrade" > Upgrade

< li > A 'FORWARDPING' option has been added to
< a href = "Documentation.htm#Conf" > shorewall.conf< / a > .
The effect of setting this variable to Yes
is the same as the effect of adding an ACCEPT
rule for ICMP echo-request in < a
href="shorewall_extension_scripts.htm">/etc/shorewall/icmpdef< / a > .
Users who have such a rule in icmpdef are
encouraged to switch to FORWARDPING=Yes.< / li >

SYN and ICMP treatment in Shorewall.
That input has led to marked improvement in
Shorewall in the last two releases.< / p >

public IP addresses and by people who want to learn
more about Shorewall than is described in the single-address
guides. Feedback on the new guide is welcome.< / p >

< li > Empty and invalid source and destination
qualifiers are now detected in the rules file.
It is a good idea to use the 'shorewall check' command
before you issue a 'shorewall restart' command be be
sure that you don't have any configuration problems
that will prevent a successful restart.< / li >

< li > Added < b > MERGE_HOSTS< / b > variable in
< a href = "Documentation.htm#Conf" > shorewall.conf< / a >
to provide saner behavior of the /etc/shorewall/hosts
file.< / li >
< li > The time that the counters were last reset
is now displayed in the heading of the 'status'
and 'show' commands.< / li >
< li > A < b > proxyarp < / b > option has been
added for entries in < a
href="Documentation.htm#Interfaces">/etc/shorewall/interfaces< / a > .
This option facilitates Proxy ARP sub-netting as described
in the Proxy ARP subnetting mini-HOWTO (< a
href="http://www.tldp.org/HOWTO/mini/Proxy-ARP-Subnet/">http://www.tldp.org/HOWTO/mini/Proxy-ARP-Subnet/< / a > ).
Specifying the proxyarp option for
an interface causes Shorewall to set
/proc/sys/net/ipv4/conf/< interface> /proxy_arp.< / li >

the new capabilities in this release. < / li >

replace the < b > routestopped< / b > option in the

easier by allowing any IP or subnet to be enabled

< p > Last weekend, I installed the CVS Web package to provide brower-based access
to the Shorewall CVS repository. Since then, I have had several instances
where my server was almost unusable due to the high load generated by website
copying tools like HTTrack and WebStripper. These mindless tools:< / p >

< p > These tools/weapons are particularly damaging when combined with CVS Web
because they doggedly follow every
link in the cgi-generated HTML resulting in
1000s of executions of the cvsweb.cgi script. Yesterday,
I spend several hours implementing measures to block
these tools but unfortunately, these measures resulted
in my server OOM-ing under even moderate load.< / p >

2003-07-22 00:06:18 +02:00
< p > Until I have the time to understand the cause of the OOM (or until I buy
more RAM if that is what is required),
CVS Web access will remain Password Protected.

problem is present in all versions of Shorewall that
support the CONTINUE policy. These previous versions
optimized away the "all2< i > < zone> < / i > " chain
and replaced it with the "all2all" chain with the usual result
that a policy of REJECT was enforced rather than the intended
CONTINUE policy.< / li >

< li > A "shorewall try" command has been added
(syntax: shorewall try < i > < configuration
directory> < / i > ). This command attempts "shorewall
-c < i > < configuration directory> < / i > start"
and if that results in the firewall being stopped due
to an error, a "shorewall start" command is executed.
The 'try' command allows you to create a new < a
href="Documentation.htm#Configs"> configuration< / a > and attempt
to start it; if there is an error that leaves your
firewall in the stopped state, it will automatically be restarted
using the default configuration (in /etc/shorewall).< / li >
< li > A new variable ADD_SNAT_ALIASES has been
added to < a href = "Documentation.htm#Conf" > /etc/shorewall/shorewall.conf< / a > .
If this variable is set to "Yes", Shorewall
will automatically add IP addresses listed
in the third column of the < a href = "Documentation.htm#Masq" >
/etc/shorewall/masq< / a > file.< / li >
< li > Copyright notices have been added to the
documenation.< / li >

1.1.16, a new parameter (< a href = "Documentation.htm#Aliases" > ADD_IP_ALIASES< / a > )
may be set to "no" (or "No") to inhibit
this behavior. This allows IP aliases created
using your distribution's network configuration
tools to be used in static NAT.<2E> < / li >

< li > Shorewall now supports alternate configuration
directories. When an alternate directory is
specified when starting or restarting Shorewall
(e.g., "shorewall -c /etc/testconf restart"), Shorewall
will first look for configuration files in the alternate
directory then in /etc/shorewall. To create an
alternate configuration simply:< br >
2003-06-23 22:24:51 +02:00
2003-07-22 00:06:18 +02:00
1. Create a New Directory< br >
2003-06-23 22:24:51 +02:00
2003-07-22 00:06:18 +02:00
2. Copy to that directory any of your configuration
files that you want to change.< br >
2003-06-23 22:24:51 +02:00
2003-07-22 00:06:18 +02:00
3. Modify the copied files as needed.< br >
2003-06-23 22:24:51 +02:00
2003-07-22 00:06:18 +02:00

2003-07-22 00:06:18 +02:00
< li > The rules for allowing/disallowing icmp
echo-requests (pings) are now moved after rules
created when processing the rules file. This allows
you to add rules that selectively allow/deny ping based
on source or destination address.< / li >
2003-06-23 22:24:51 +02:00
2003-07-22 00:06:18 +02:00

< li > Previous versions of Shorewall have
an implementation of Static NAT which violates the
principle of least surprise.<2E> NAT only occurs for packets
arriving at (DNAT) or send from (SNAT) the interface
named in the INTERFACE column of /etc/shorewall/nat.
Beginning with version 1.1.6, NAT effective regardless
of which interface packets come from or are destined to.
To get compatibility with prior versions, I have added
a new "ALL < a href = "NAT.htm#AllInterFaces" > "ALL INTERFACES"<22>
column to /etc/shorewall/nat< / a > . By placing "no"
or "No" in the new column, the NAT behavior of prior
versions may be retained.<2E> < / li >
< li > The treatment of < a

will now create this rule automatically when you place
the name of the remote peer's zone in a new GATEWAY ZONE column
in /etc/shorewall/tunnels.<2E> < / li >
