This is a minor release of Shorewall. Problems Corrected since version 1.4.9: 1. The column descriptions in the action.template file did not match the column headings. That has been corrected. 2. The presence of IPV6 addresses on devices generates error messages during [re]start if ADD_IP_ALIASES=Yes or ADD_SNAT_ALIASES=Yes are specified in /etc/shorewall/shorewall.conf. 3. Shorewall now tried to avoid sending an ICMP response to broadcasts. Migration Issues: None. New Features: 1) The INTERFACE column in the /etc/shorewall/masq file may now specify a destination list. Example: #INTERFACE SUBNET ADDRESS eth0:192.0.2.3,192.0.2.16/28 eth1 If the list begins with "!" then SNAT will occur only if the destination IP address is NOT included in the list. 2) Output traffic control rules (those with the firewall as the source) may now be qualified by the effective userid and/or effective group id of the program generating the output. This feature is courtesy of Frédéric LESPEZ. A new USER column has been added to /etc/shorewall/tcrules. It may contain : []:[] The colon is optionnal when specifying only a user. Examples : john: / john / :users / john:users 3) A "detectnets" interface option has been added for entries in /etc/shorewall/interfaces. This option automatically taylors the definition of the zone named in the ZONE column to include just those hosts that have routes through the interface named in the INTERFACE column. The named interface must be UP when Shorewall is [re]started. WARNING: DO NOT SET THIS OPTION ON YOUR INTERNET INTERFACE!
