Shorewall 3.3.0 Note to users upgrading from Shorewall 2.x or 3.0 Most problems associated with upgrades come from two causes: - The user didn't read and follow the migration considerations in these release notes. - The user mis-handled the /etc/shorewall/shorewall.conf file during upgrade. Shorewall is designed to allow the default behavior of the product to evolve over time. To make this possible, the design assumes that you will not replace your current shorewall.conf file during upgrades. If you feel absolutely compelled to have the latest comments and options in your shorewall.conf then you must proceed carefully. While you are at it, if you have a file named /etc/shorewall/rfc1918 then please check that file. If it has addresses listed that are NOT in one of these three ranges, then please rename the file to /etc/shorewall/rfc1918.old. 10.0.0.0 - 10.255.255.255 172.16.0.0 - 172.31.255.255 192.168.0.0 - 192.168.255.255 If you have a file named /etc/shorewall/modules, please remove it. The default modules file is now located in /usr/share/shorewall/ (see the "Migration Considerations" below). Please see the "Migration Considerations" below for additional upgrade information. Problems Corrected in 3.3.0 None. Other changes in 3.3.0 1) Support for dynamic zones (DYNAMIC_ZONES=Yes in shorewall.conf and the /sbin/shorewall "add" and "delete" commands) has been removed. Please use ipsets to implement dynamic zones as described in http://www.shorewall.net/DynamicZones.html. 2) The 'try' command has been re-implemented. The command now does the following: - shorewall save - shorewall restart - if the restart is not successful, the configuration is automatically restored - otherwise, if a timeout is given then - sleep for the number of seconds specified and - shorewall restore Migration Considerations: 1) Support for dynamic zones (DYNAMIC_ZONES=Yes in shorewall.conf and the /sbin/shorewall "add" and "delete" commands) has been removed. Please use ipsets to implement dynamic zones as described in http://www.shorewall.net/DynamicZones.html. New Features: None.
