<h3>What is Shorewall?</h3>
|
||||
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 connection state tracking
|
||||
capabilities.<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 /> <h3>Getting
|
||||

    None.<br /> <br /> New Features: </p> <ol><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/LogAndAccept and in
|
||||
that file, you would add the two rules:<br />
|
||||
        LOG:info<br />
|
||||
        ACCEPT<br />
|
||||
<br /></li></ol> <p><b>12/03/2003 - Support Torch Passed</b> <b><img

|
||||
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/LogAndAccept and in that file, you would add the two
|
||||
rules:<br>
|
||||
LOG:info<br>
|
||||
ACCEPT<br>
|
||||
<br>

|

New Features:<br /> <ol><li>A new QUEUE action has been introduced for
|
||||
rules. QUEUE allows you to pass connection requests to a user-space filter
|
||||
such as ftwall (http://p2pwall.sourceforge.net). The ftwall program allows
|
||||
for effective filtering of p2p applications such as Kazaa. For example, to
|
||||
use ftwall to filter P2P clients in the 'loc' zone, you would add
|
||||
the following rules:<br /> <br />    QUEUE  
|
||||
loc        
|
||||
net    tcp<br />    QUEUE  
|
||||
loc        
|
||||
net    udp<br />    QUEUE  
|
||||
loc        
|
||||
fw     udp<br /> <br /> You would normally want
|
||||
to place those three rules BEFORE any ACCEPT rules for loc->net udp or
|
||||
tcp.<br /> <br /> Note: When the protocol specified is TCP ("tcp",
|
||||
"TCP" or "6"), Shorewall will only pass connection requests
|
||||
(SYN packets) to user space. This is for compatibility with ftwall.</li><li>A
|
||||
BLACKLISTNEWNONLY option has been added to shorewall.conf. When this option
|
||||
is set to "Yes", the blacklists (dynamic and static) are only
|
||||
consulted for new connection requests. When set to "No" (the default
|
||||
if the variable is not set), the blacklists are consulted on every packet.<br />
|
||||
<br /> Setting this option to "No" allows blacklisting to stop
|
||||
existing connections from a newly blacklisted host but is more expensive in
|
||||
terms of packet processing time. This is especially true if the blacklists
|
||||
contain a large number of entries.</li><li>Chain names used in the
|
