Problems corrected in 4.0.0 Beta 1.
1) The commands "shorewall add/delete <interface> <zone>" no longer
case lots of error messages to be issued.
1) If an interfaces named in the SOURCE column of /etc/shorewall/masq had a
default route, an iptables-restore failure previously resulted.
2) A port list in a SOURCE PORT(S) column now works when the DEST
PORT(S) list is empty.
Other changes in Shorewall 4.0.0 Beta 2.
3) A run-time error no longer occurs when an IP address is specified
in the GATEWAY column of /etc/shorewall/providers.
Other changes in Shorewall 4.0.0 Beta 1.
1) The "shorewall show zones" command now flags zone members that have
been added using "shorewall add" by preceding them with a plus sign
("+").
Example:
Shorewall 3.9.4 Zones at gateway - Mon May 14 07:48:16 PDT 2007
fw (firewall)
net (ipv4)
eth0:0.0.0.0/0

+eth1:0.0.0.0/0
dmz (ipv4)
eth3:0.0.0.0/0
vpn (ipv4)
tun+:0.0.0.0/0
In the above output, "eth1:0.0.0.0/0" was dynamically added to the
'loc' zone. As part of this change, "shorewall delete" will only
delete entries that have been added dynamically. In earlier
versions, any entry could be deleted although the ruleset was only
changed by deleting entries that had been added dynamically.
2) The 'shorewall version' command now lists the version of the
installed compiler(s):

Mini-Perl has a substantial disk and RAM footprint.
b) Because of the gross incompatibilities between the new compiler and the
old (see below), migration to the new compiler must be voluntary.
c) By allowing Shorewall-perl to co-exist with the current
Shorewall stable release (3.4), I'm hoping that the new compiler
will get more testing and validation than it would if I were to
package it with a new development version of Shorewall itself.
d) Along the same vein, I think that users will be more likely to
experiment with the new compiler if they can easily fall back to
the old one if things get sticky.
