12/20/2002 - Shorewall 1.3.12 Beta 2 

1. "shorewall refresh" now reloads the traffic shaping rules (tcrules and tcstart).
2. "shorewall debug [re]start" now turns off debugging after an error occurs. This places the point of the failure near the end of the trace rather than up in the middle of it.
3. "shorewall [re]start" has been speeded up by more than 40% with my configuration. Your milage may vary.
4. A "shorewall show classifiers" command has been added which shows the current packet classification filters. The output from this command is also added as a separate page in "shorewall monitor"
5. ULOG (must be all caps) is now accepted as a valid syslog level and causes the subject packets to be logged using the ULOG target rather than the LOG target. This allows you to run ulogd (available from http://www.gnumonks.org/projects/ulogd) and log all Shorewall messages to a separate log file.
6. If you are running a kernel that has a FORWARD chain in the mangle table ("shorewall show mangle" will show you the chains in the mangle table), you can set MARK_IN_FORWARD_CHAIN=Yes in shorewall.conf. This allows for marking input packets based on their destination even when you are using Masquerading or SNAT.
7. I have cluttered up the /etc/shorewall directory with empty 'init', 'start', 'stop' and 'stopped' files. If you already have a file with one of these names, don't worry -- the upgrade process won't overwrite your file.

12/12/2002 - Mandrake Multi Network Firewall

12/7/2002 - Shorewall Support for Mandrake 9.0

Two months and 3 days after I pre-ordered Mandrake 9.0, it was finally delivered. I have installed 9.0 on one of my systems and I am now in a position to support Shorewall users who run Mandrake 9.0.

12/6/2002 -  Debian 1.3.11a Packages Available

Apt-get sources listed at http://security.dsi.unimi.it/~lorenzo/debian.html.

12/3/2002 - Shorewall 1.3.11a

This is a bug-fix roll up which includes Roger Aich's fix for DNAT with excluded subnets (e.g., "DNAT foo!bar ..."). Current 1.3.11 users who don't need rules of this type need not upgrade to 1.3.11.

Juraj Ontkanin has produced a PDF containing the Shorewall 1.3.11 documenation. the PDF may be downloaded from

11/24/2002 - Shorewall 1.3.11

In this version:

• A 'tcpflags' option has been added to entries in /etc/shorewall/interfaces. This option causes Shorewall to make a set of sanity check on TCP packet header flags.
• It is now allowed to use 'all' in the SOURCE or DEST column in a rule. When used, 'all' must appear by itself (in may not be qualified) and it does not enable intra-zone traffic. For example, the rule
  
      ACCEPT loc all tcp 80
  
  does not enable http traffic from 'loc' to 'loc'.
• Shorewall's use of the 'echo' command is now compatible with bash clones such as ash and dash.
• fw->fw policies now generate a startup error. fw->fw rules generate a warning and are ignored
