1) Elimination of the "shorewall monitor" command. 2) The /etc/shorewall/ipsec and /etc/shorewall/zones file are combined into a single /etc/shorewall/zones file. This is done in an upwardly-compatible way so that current users can continue to use their existing files. 3) Support has been added for the arp_ignore interface option. 4) DROPINVALID has been removed from shorewall.conf. Behavior is as if DROPINVALID=No was specified. 5) The 'nobogons' option and BOGON_LOG_LEVEL are removed. 6) Error and warning messages have been made easier to spot by using capitalization (e.g., ERROR: and WARNING:). 7) The /etc/shorewall/policy file now contains a new connection policy and a policy for ESTABLISHED packets. Useful for users of snort-inline who want to pass all packets to the QUEUE target. 8) A new 'critical' option has been added to /etc/shorewall/routestopped. Shorewall insures communication between the firewall and 'critical' hosts throughout start, restart, stop and clear. Useful for diskless firewall's with NFS-mounted file systems, LDAP servers, Crossbow, etc. 9) Macros. Macros are very similar to actions but are easier to use, allow parameter substitution and are more efficient. Almost all of the standard actions have been converted to macros in the EXPERIMENTAL branch. 10) The default value of ADD_IP_ALIASES in shorewall.conf is changed to No. 11) If you have 'make' installed on your firewall, then when you use the '-f' option to 'shorewall start' (as happens when you reboot), if your /etc/shorewall/ directory contains files that were modified after Shorewall was last restarted then Shorewall is started using the config files rather than using the saved configuration. git-svn-id: https://shorewall.svn.sourceforge.net/svnroot/shorewall/trunk@2409 fbd18981-670d-0410-9b5c-8dc0c1a9a2bb

#
|
|
# The default DROP common rules
|
|
#
|
|
# This action is invoked before a DROP policy is enforced. The purpose of the action
|
|
# is:
|
|
#
|
|
# a) Avoid logging lots of useless cruft.
|
|
# b) Ensure that 'auth' requests are rejected, even if the policy is DROP.
|
|
# Otherwise, you may experience problems establishing connections with
|
|
# servers that use auth.
|
|
# c) Ensure that certain ICMP packets that are necessary for successful
|
|
# internet operation are always ACCEPTed.
|
|
#
|
|
# IF YOU ARE HAVING CONNECTION PROBLEMS, CHANGING THIS FILE WON'T HELP!!!!!!!!!!!!
