packet filter facility built into the 2.4 and later Linux kernels.</li>
|
||||
<li>ipchains - the packet filter facility built into the 2.2

Linux kernels. Also the name of the utility program used to configure

compatibility mode.</li>
|

<li>iptables - the utility program used to configure and

compatibility mode).</li>

<h3>What is Shorewall?</h3>
|
||||
<div style="margin-left: 40px;">The Shoreline Firewall, more
|
||||
commonly known as "Shorewall", is
|
||||
high-level tool for configuring Netfilter. You describe your
|
||||
firewall/gateway requirements using entries in a set of configuration
|
||||
files. Shorewall reads those configuration files and with the help of
|
||||
the iptables utility, Shorewall configures Netfilter to match your
|
||||
requirements. Shorewall can be used on a dedicated firewall system, a
|
||||
multi-function gateway/router/server or on a standalone GNU/Linux
|
||||
system. Shorewall does not use Netfilter's ipchains compatibility mode
|
||||
and can thus take advantage of Netfilter's <a
|
||||
href="http://www.cs.princeton.edu/%7Ejns/security/iptables/iptables_conntrack.html"
|
||||
target="_top">connection
|
||||
state tracking
|
||||
capabilities</a>.<br>
|
||||
<br>
|
||||
Shorewall is <span style="text-decoration: underline;">not</span> a
|
||||
daemon. Once Shorewall has configured Netfilter, it's job is complete
|
||||
although the <a href="starting_and_stopping_shorewall.htm">/sbin/shorewall
|
||||
program can be used at any time to monitor the Netfilter firewall</a>.<br>
|
||||
</div>
|
||||
<h3>Getting Started with Shorewall</h3>
|
||||
<div style="margin-left: 40px;">New to Shorewall? Start by
|
||||
selecting the <a href="shorewall_quickstart_guide.htm">QuickStart Guide</a>
|
||||
that most
|
||||
closely match your environment and follow the step by step instructions.<br>
|
||||
</div>
|
||||
<h3>Looking for Information?</h3>
|
||||
<div style="margin-left: 40px;">The <a
|
||||
href="Documentation_Index.html">Documentation
|
||||
Index</a> is a good place to start as is the Quick Search in the frame
|
||||
above. </div>
|
||||
<h3>Running Shorewall on Mandrake with a two-interface setup?</h3>

<p><b>1/30/2004 - Shorewall 1.4.10</b></p>
|
||||
<p>Problems Corrected since version 1.4.9</p>
|
||||
<ol>
|
||||
<li>The column descriptions in the action.template file did not
|
||||
match the column headings. That has been corrected.</li>
|
||||
<li>The presence of IPV6 addresses on devices generated error
|

<li>Shorewall now tried to avoid sending an ICMP response to
|

broadcasts and smurfs.</li>
|
||||
<li>Specifying "-" or "all" in the PROTO column of an action no

|

Migragion Issues:<br>
|

<br>
|

None.<br>
|
||||
<br>
|
||||
New Features:<br>
|
||||
<ol>
|
||||
<li>The INTERFACE column in the /etc/shorewall/masq file may
|
||||
now specify a destination list. <br>
|
||||
<br>
|
||||
Example:<br>
|
||||
<br>
|
||||
#INTERFACE
|
||||
SUBNET ADDRESS<br>
|
||||
eth0:192.0.2.3,192.0.2.16/28 eth1<br>
|
||||
<br>
|
||||
If the list begins with "!" then SNAT will occur only if the
|
||||
destination IP address is NOT included in the list.<br>
|
||||
<br>
|
||||
</li>
|
||||
<li>Output traffic control rules (those with the firewall as
|
||||
the source) may now be qualified by the effective userid and/or
|
||||
effective group id of the program generating the output. This feature
|
||||
is courtesy of Frédéric LESPEZ.<br>
|
||||
<br>
|
||||
A new USER column has been added to /etc/shorewall/tcrules. It may
|
||||
contain :<br>
|
||||
<br>
|
||||
[<user name or number>]:[<group
|
||||
name or number>]<br>
|
||||
<br>
|
||||
The colon is optional when specifying only a user.<br>
|
||||
<br>
|
||||
Examples : john: / john / :users /
|
||||
john:users<br>
|
||||
<br>
|
||||
</li>
|
||||
<li>A "detectnets" interface option has been added for entries
|
||||
in /etc/shorewall/interfaces. This option automatically taylors the
|
||||
definition of the zone named in the ZONE column to include just
|
||||
those hosts that have routes through the interface named in the
|
||||
INTERFACE column. The named interface must be UP when Shorewall is
|
||||
[re]started.<br>
|
||||
<br>
|
||||
WARNING: DO NOT SET THIS OPTION ON YOUR INTERNET INTERFACE! <br>

<p><b>1/17/2004 - FAQ Wiki Available </b></p>
|
||||
<p>It has been asserted that the use of CVS for maintaining the
|
||||
Shorewall documentation has been a barrier to community participation.
|
||||
To test this theory, Alex Martin <a
|
||||
href="http://wiki.rettc.com/wiki.phtml?title=Wiki_Shorewall_FAQ">has
|
||||
created a Wiki</a> and with the help of Mike Noyes has populated the
|
||||
Wiki with the Shorewall FAQ. <br>
|
||||
</p>
|
||||
<p><b>1/13/2004 - Shorewall 1.4.9 </b><b> </b></p>
|
||||
<p>Problems Corrected since version 1.4.8:</p>
|
||||
<ol>
|
||||
<li>There has been a low continuing level of confusion over the
|
||||
terms "Source NAT" (SNAT) and "Static NAT". To avoid future confusion,
|
||||
all instances of "Static NAT" have been replaced with "One-to-one NAT"
|
||||
in the documentation and configuration files.</li>
|
||||
<li>The description of NEWNOTSYN in shorewall.conf has been
|
||||
reworded for clarity.</li>
|
||||
<li>Wild-card rules (those involving "all" as SOURCE or DEST)
|
||||
will no longer produce an error if they attempt to add a rule that
|
||||
would override a NONE policy. The logic for expanding these wild-card
|
||||
rules now simply skips those (SOURCE,DEST) pairs that have a NONE
|
||||
policy.</li>
|
||||
<li>DNAT rules that also specified SNAT now work reliably.
|
||||
Previously, there were cases where the SNAT specification was
|
||||
effectively ignored.<br>
|
||||
</li>
|
||||
</ol>
|
||||
<p>Migration Issues:</p>
|
||||
<p> None.<br>
|
||||
<br>
|
||||
New Features: </p>
|
||||
<ol>
|
||||
<li>The documentation has been completely rebased to Docbook
|
||||
XML. The documentation is now released as separate HTML and XML
|
||||
packages.<br>
|
||||
</li>
|
||||
<li>To cut down on the number of "Why are these ports closed
|
||||
rather than stealthed?" questions, the SMB-related rules in
|
||||
/etc/shorewall/common.def have been changed from 'reject' to 'DROP'.</li>
|
||||
<li>For easier identification, packets logged under the
|
||||
'norfc1918' interface option are now logged out of chains named
|
||||
'rfc1918'. Previously, such packets were logged under chains named
|
||||
'logdrop'.</li>
|
||||
<li>Distributors and developers seem to be regularly inventing
|
||||
new naming conventions for kernel modules. To avoid the need to change
|
||||
Shorewall code for each new convention, the MODULE_SUFFIX option has
|
||||
been added to shorewall.conf. MODULE_SUFFIX may be set to the suffix
|
||||
for module names in your particular distribution. If MODULE_SUFFIX is
|
||||
not set in shorewall.conf, Shorewall will use the list "o gz ko o.gz".<br>
|
||||
<br>
|
||||
To see what suffix is used by your distribution:<br>
|
||||
<br>
|
||||
ls /lib/modules/$(uname -r)/kernel/net/ipv4/netfilter<br>
|
||||
<br>
|
||||
All of the files listed should have the same suffix (extension). Set
|
||||
MODULE_SUFFIX to that suffix.<br>
|
||||
<br>
|
||||
Examples:<br>
|
||||
<br>
|
||||
If all files end in ".kzo" then set
|
||||
MODULE_SUFFIX="kzo"<br>
|
||||
If all files end in ".kz.o" then set
|
||||
MODULE_SUFFIX="kz.o"</li>
|
||||
<li>Support for user defined rule ACTIONS has been implemented
|
||||
through two new files:<br>
|
||||
<br>
|
||||
/etc/shorewall/actions - used to list the user-defined ACTIONS.<br>
|
||||
/etc/shorewall/action.template - For each user defined <action>,
|
||||
copy this file to /etc/shorewall/action.<action> and add the
|
||||
appropriate rules for that <action>. Once an <action> has
|
||||
been defined, it may be used like any of the builtin ACTIONS (ACCEPT,
|
||||
DROP, etc.) in /etc/shorewall/rules.<br>
|
||||
<br>
|
||||
Example: You want an action that logs a packet at the 'info' level and
|
||||
accepts the connection.<br>
|
||||
<br>
|
||||
In /etc/shorewall/actions, you would add:<br>
|
||||
<br>
|
||||
LogAndAccept<br>
|
||||
<br>
|
||||
You would then copy /etc/shorewall/action.template to
|
||||
/etc/shorewall/action.LogAndAccept and in that file, you would add the
|
||||
two
|
||||
rules:<br>
|
||||
LOG:info<br>
|
||||
ACCEPT<br>
|
||||
</li>
|
||||
<li>The default value for NEWNOTSYN in shorewall.conf is now
|
||||
"Yes" (non-syn TCP packets that are not part of an existing connection
|
||||
are filtered according to the rules and policies rather than being
|
||||
dropped). I have made this change for two reasons:<br>
|
||||
<br>
|
||||
a) NEWNOTSYN=No tends to result in lots of "stuck" connections since
|
||||
any timeout during TCP session tear down results in the firewall
|
||||
dropping all of the retries.<br>
|
||||
<br>
|
||||
b) The old default of NEWNOTSYN=No and LOGNEWNOTSYN=info resulted in
|
||||
lots of confusing messages when a connection got "stuck". While I could
|
||||
have changed the default value of LOGNEWNOTSYN to suppress logging, I
|
||||
dislike defaults that silently throw away packets.</li>
|
||||
<li>The common.def file now contains an entry that silently
|
||||
drops ICMP packets with a null source address. Ad Koster reported a
|
||||
case where these were occuring frequently as a result of a broken
|
||||
system on his external network.<br>

||||

</ul>
|
||||
The Shoreline Firewall, more commonly known as "Shorewall", is
|
||||
high-level tool for configuring Netfilter. You describe your
|
||||
firewall/gateway requirements using entries in a set of
|
||||
configuration files. Shorewall reads those configuration files and
|
||||
with the help of the iptables utility, Shorewall configures
|
||||
Netfilter to match your requirements. Shorewall can be used on a
|
||||
dedicated firewall system, a multi-function gateway/router/server
|
||||
or on a standalone GNU/Linux system. Shorewall does not use
|
||||
Netfilter's ipchains compatibility mode and can thus take advantage
|
||||
of Netfilter's <a

|

state tracking capabilities</a>.

<h2>Running Shorewall on Mandrake with a two-interface setup?</h2>
|
||||
If so, the documentation on this site will not apply
|
||||
directly to your setup. If you want to use the documentation that

<p><b>1/30/2004 - Shorewall 1.4.10</b></p>
|
||||
<p>Problems Corrected since version 1.4.9</p>
|
||||
<ol>
|
||||
<li>The column descriptions in the action.template file did not
|
||||
match the column headings. That has been corrected.</li>
|
||||
<li>The presence of IPV6 addresses on devices generated error
|
||||
messages during [re]start if ADD_IP_ALIASES=Yes or ADD_SNAT_ALIASES=Yes
|

|
||||
<li>Shorewall now tried to avoid sending an ICMP response to

|

<li>Specifying "-" or "all" in the PROTO column of an action no

|
||||
Migragion Issues:<br>
|
||||
<br>
|
||||
None.<br>
|
||||
<br>
|
||||
New Features:<br>
|
||||
<ol>
|
||||
<li>The INTERFACE column in the /etc/shorewall/masq file may
|
||||
now specify a destination list. <br>
|
||||
<br>
|
||||
Example:<br>
|
||||
<br>
|
||||
#INTERFACE
|
||||
SUBNET ADDRESS<br>
|
||||
eth0:192.0.2.3,192.0.2.16/28 eth1<br>
|
||||
<br>
|
||||
If the list begins with "!" then SNAT will occur only if the
|
||||
destination IP address is NOT included in the list.<br>
|
||||
<br>
|
||||
</li>
|
||||
<li>Output traffic control rules (those with the firewall as
|
||||
the
|
||||
source) may now be qualified by the effective userid and/or effective
|
||||
group id of the program generating the output. This feature is courtesy
|
||||
of Frédéric LESPEZ.<br>
|
||||
<br>
|
||||
A new USER column has been added to /etc/shorewall/tcrules. It may
|
||||
contain :<br>
|
||||
<br>
|
||||
[<user name or number>]:[<group
|
||||
name or number>]<br>
|
||||
<br>
|
||||
The colon is optional when specifying only a user.<br>
|
||||
<br>
|
||||
Examples : john: / john / :users /
|
||||
john:users<br>
|
||||
<br>
|
||||
</li>
|
||||
<li>A "detectnets" interface option has been added for entries
|
||||
in
|
||||
/etc/shorewall/interfaces. This option automatically taylors the
|
||||
definition of the zone named in the ZONE column to include just
|
||||
those
|
||||
hosts that have routes through the interface named in the INTERFACE
|
||||
column. The named interface must be UP when Shorewall is [re]started.<br>
|
||||
<br>
|
||||
WARNING: DO NOT SET THIS OPTION ON YOUR INTERNET INTERFACE!

<p><b>1/17/2004 - FAQ Wiki Available </b></p>
|
||||
It has been asserted that the use of CVS for maintaining the
|
||||
Shorewall documentation has been a barrier to community participation.
|
||||
To test this theory, Alex Martin <a
|
||||
href="http://wiki.rettc.com/wiki.phtml?title=Wiki_Shorewall_FAQ">has
|
||||
created a Wiki</a> and with the help of Mike Noyes has populated the
|
||||
Wiki with the Shorewall FAQ.
|
||||
<p><b>1/13/2004 - Shorewall 1.4.9</b> <b><br>
|
||||
</b></p>
|
||||
<p>Problems Corrected since version 1.4.8:<br>
|
||||
</p>
|
||||
<ol>
|
||||
<li>There has been a low continuing level of confusion over the
|
||||
terms "Source NAT" (SNAT) and "Static NAT". To avoid future
|
||||
confusion, all instances of "Static NAT" have been replaced with
|
||||
"One-to-one NAT" in the documentation and configuration files.</li>
|
||||
<li>The description of NEWNOTSYN in shorewall.conf has been
|
||||
reworded for clarity.</li>
|
||||
<li>Wild-card rules (those involving "all" as SOURCE or DEST)
|
||||
will
|
||||
no longer produce an error if they attempt to add a rule that would
|
||||
override a NONE policy. The logic for expanding these wild-card
|
||||
rules now simply skips those (SOURCE,DEST) pairs that have a NONE
|
||||
policy.</li>
|
||||
<li>DNAT rules that also specified SNAT now work reliably.
|
||||
Previously,
|
||||
there were cases where the SNAT specification was effectively ignored.</li>
|
||||
</ol>
|
||||
<p>Migration Issues:<br>
|
||||
<br>
|
||||
None.<br>
|
||||
<br>
|
||||
New Features:<br>
|
||||
</p>
|
||||
<ol>
|
||||
<li>The documentation has been completely rebased to Docbook
|
||||
XML. The
|
||||
documentation is now released as separate HTML and XML packages.</li>
|
||||
<li>To cut down on the number of "Why are these ports closed
|
||||
rather
|
||||
than stealthed?" questions, the SMB-related rules in
|
||||
/etc/shorewall/common.def have been changed from 'reject' to
|
||||
'DROP'.</li>
|
||||
<li>For easier identification, packets logged under the
|
||||
'norfc1918'
|
||||
interface option are now logged out of chains named 'rfc1918'.
|
||||
Previously, such packets were logged under chains named
|
||||
'logdrop'.</li>
|
||||
<li>Distributors and developers seem to be regularly inventing
|
||||
new
|
||||
naming conventions for kernel modules. To avoid the need to change
|
||||
Shorewall code for each new convention, the MODULE_SUFFIX option
|
||||
has been added to shorewall.conf. MODULE_SUFFIX may be set to the
|
||||
suffix for module names in your particular distribution. If
|
||||
MODULE_SUFFIX is not set in shorewall.conf, Shorewall will use the
|
||||
list "o gz ko o.gz".<br>
|
||||
<br>
|
||||
To see what suffix is used by your distribution:<br>
|
||||
<br>
|
||||
ls /lib/modules/$(uname -r)/kernel/net/ipv4/netfilter<br>
|
||||
<br>
|
||||
All of the files listed should have the same suffix (extension).
|
||||
Set MODULE_SUFFIX to that suffix.<br>
|
||||
<br>
|
||||
Examples:<br>
|
||||
<br>
|
||||
If all files end in ".kzo" then set
|
||||
MODULE_SUFFIX="kzo"<br>
|
||||
If all files end in ".kz.o" then set
|
||||
MODULE_SUFFIX="kz.o"</li>
|
||||
<li>Support for user defined rule ACTIONS has been implemented
|
||||
through two new files:<br>
|
||||
<br>
|
||||
/etc/shorewall/actions - used to list the user-defined ACTIONS.<br>
|
||||
/etc/shorewall/action.template - For each user defined
|
||||
<action>, copy this file to
|
||||
/etc/shorewall/action.<action> and add the appropriate rules
|
||||
for that <action>. Once an <action> has been defined,
|
||||
it may be used like any of the builtin ACTIONS (ACCEPT, DROP, etc.)
|
||||
in /etc/shorewall/rules.<br>
|
||||
<br>
|
||||
Example: You want an action that logs a packet at the 'info' level
|
||||
and accepts the connection.<br>
|
||||
<br>
|
||||
In /etc/shorewall/actions, you would add:<br>
|
||||
<br>
|
||||
LogAndAccept<br>
|
||||
<br>
|
||||
You would then copy /etc/shorewall/action.template to
|
||||
/etc/shorewall/action.LogAndAccept and in that file, you would add the
|
||||
two
|
||||
rules:<br>
|
||||
LOG:info<br>
|
||||
ACCEPT</li>
|
||||
<li>The default value for NEWNOTSYN in shorewall.conf is now
|
||||
"Yes" (non-syn
|
||||
TCP packets that are not part of an existing connection are filtered
|
||||
according to the rules and policies rather than being dropped). I have
|
||||
made this change for two reasons:<br>
|
||||
<br>
|
||||
a) NEWNOTSYN=No tends to result in lots of "stuck" connections since
|
||||
any timeout during TCP session tear down results in the firewall
|
||||
dropping all of the retries.<br>
|
||||
<br>
|
||||
b) The old default of NEWNOTSYN=No and LOGNEWNOTSYN=info resulted in
|
||||
lots of confusing messages when a connection got "stuck". While I could
|
||||
have changed the default value of LOGNEWNOTSYN to suppress logging, I
|
||||
dislike defaults that silently throw away packets.</li>
|
||||
<li>The common.def file now contains an entry that silently
|
||||
drops ICMP
|
||||
packets with a null source address. Ad Koster reported a case where
|
||||
these were occuring frequently as a result of a broken system on his
|
||||
external network.</li>
