|
<ol>
|
|
|
|
|
|
<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>

|
|
|
|
|
<br>
|
|
|
|
|
|
</li>
|
|
|
|
|
|
<li>Any file may include an INCLUDE directive. An INCLUDE directive
|
|
|
|
|
|
consists of the word INCLUDE followed by a file name and causes the contents
|
|
|
|
|
|
of the named file to be logically included into the file containing the INCLUDE.
|
|
|
|
|
|
File names given in an INCLUDE directive are assumed to reside in /etc/shorewall
|
|
|
|
|
|
or in an alternate configuration directory if one has been specified for
|
|
|
|
|
|
the command. <br>

INCLUDE's may be nested to a level of 3 -- further nested INCLUDE directives
|
|
|

are ignored with a warning message.<br>

|
</li>
|
|
|
|
|
|
<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>
|
|
|

about how this new option may affect your configuration.<br>
