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.
