The bad news:
There are a number of incompatibilities between the Perl-based compiler

and the Bourne-shell one. Some of these will probably go away by first
official release but some will not.
a) The Perl-based compiler requires the following capabilities in your
kernel and iptables.
- addrtype match
- conntrack match
- multiport match
- addrtype match (may be relaxed later)
- conntrack match (may be relaxed later)
- multiport match (will not be relaxed)
These capabilities are in current distributions.
b) The Bourne-shell compiler goes to great pain (in some cases) to
break very long port lists ( > 15 where port ranges in lists count
as two ports) into individual rules. I'm removing the ugliness
required to do that (at least initially). The new compiler just
gives you an error. It will also give you an error if you insert a
port range into a port list and you don't have extended multiport
support. Now that Netfilter has features to deal reasonably with
port lists, I see no reason to duplicate those features in
Shorewall.

This is a perminent change. The old zone-based rules have never
worked right and this is a good time to replace them. I've tried to
make the new syntax cover the most common cases without requiring
change to existing files. In particular, it will handle the tos file
released with Shorewall 1.4 and earlier.
i) Currently, support for ipsets is untested. That will change with
future releases but one thing is certain -- Shorewall is now out of the

By default, the old Bourne-shell based compiler will be used.
There is one change in Shorewall operation that is triggered when
/usr/share/shorewall-perl exists and is either a directory or a symbolic
link that points to a directory: Your params file will be processed
with the shell's '-a' option set which will automatically export any
variables that you set or create in that file. Since the params file is
processed before shorewall.conf, using the -a option assures that the
settings of your params variables are available to the new compiler
should it be used.
To use the new compiler, add this to shorewall.conf:
To actually use the new compiler, add this to shorewall.conf:
SHOREWALL_PERL=Yes
SHOREWALL_COMPILER=perl
If you add this setting to /etc/shorewall/shorewall.conf then by
default, the new compiler will be used on the system. If you add it to
shorewall.conf in a separate directory (such as a Shorewall-lite export
directory) then the new compiler will only be used when you compile
from that directory.
Regardless of the setting of SHOREWALL_COMPILER, there is one change in
Shorewall operation that is triggered simply by installing
shorewall-perl. Your params file will be processed with the shell's
'-a' option which causes any variables that you set or create in that
file to be automatically exported. Since the params file is processed
before shorewall.conf, using -a insures that the settings of your
params variables are available to the new compiler should it's use be
specified in shorewall.conf.
