Changes since 1.2.13
|
||||
Changes since 1.3.0
|
||||
|
||||
1. Changed all file versions to 1.3
|
||||
1. Corrected policy handling for "all z CONTINUE" policies.
|
||||
2. Corrected problems with "-" as LOGLEVEL in the policy file.
|
||||
3. Added /etc/shorewall/rfc1918 file for defining the behavior of the
|
||||
'norfc1918' interface option.
|
||||
4. Avoided forwarding rules between zones on the same interface when 'multi'
|
||||
isn't specified on that interface.
|
||||
|
||||
2. Changed the rules file and firewall file to implement the new forwarding
|
||||
and redirection syntax.
|
||||
|
||||
3. Removed the sample rules from the rules file -- the quickstart samples
|
||||
should provide those sample rules.
|
||||
|
||||
4. Added a silent Auth reject rule to common.def.
|
||||
|
||||
5. Changed the handling of the nat table to have a separate chain for each
|
||||
source zone.
|
||||
|
||||
6. Removed the code that tested each rules column for "none" -- this was never
|
||||
documented and was there to support the brain-dead parameterized samples.
|
||||
|
||||
7. Reworked the chain structure in the filter table so that each interface has
|
||||
its own input and forward chain.
|
||||
|
||||
8. Added logic to allow a subzone to be excluded from a DNAT or REDIRECT rule.
|
||||
|
||||
9. Removed white list capability
|
||||
|
||||
10. Added 'filterping' interface option.

This is a major release of Shorewall.
|
||||
This is a minor release of Shorewall.
|
||||
|
||||
In this release:
|
||||
|
||||
1. The rules syntax for port forwarding and port redirection has been
|
||||
simplified.
|
||||
|
||||
2. Compatibility has been maintained with version 1.2 configurations so
|
||||
that users may migrate their configuration at their convenience.
|
||||
|
||||
WARNING: Compatibility has NOT been maintained with the parameterized
|
||||
sample configurations which were withdrawn on 4/8/2002. Users
|
||||
still employing one of those samples must upgrade to the
|
||||
latest samples before running Shorewall 1.3 (Beta or Release).
|
||||
|
||||
3. You may now exclude zone A from a DNAT or REDIRECT rule that applies
|
||||
to zone B where zone A is a subzone of sone B.
|
||||
|
||||
4. The whitelist capability has been deimplemented. With recent changes
|
||||
to the firewall structure and change 3. above, white lists are now
|
||||
best implemented using zones as shown at:
|
||||
|
||||
http://www.shorewall.net/whitelisting_under_shorewall.htm
|
||||
|
||||
5. A 'filterping' interface option has been added to allow the
|
||||
rules and policy files to control the handling of ICMP echo-request
|
||||
(ping) requests that are addressed to the firewall.
|
||||
1. The handling of "all z CONTINUE" policies has been corrected. Use of
|
||||
these policies greatly simplifies whitelisting and other nested zone
|
||||
configuration.
|
||||
|
||||
2. Added an /etc/shorewall/rfc1918 configuration file for defining the
|
||||
behavior of the 'norfc1918' interface option.
