What is it?

The Shoreline Firewall, more commonly known as "Shorewall", is a Netfilter (iptables) based firewall that can be used on a dedicated firewall system, a multi-function gateway/router/server or on a standalone GNU/Linux system.

News

11/24/2002 - Shorewall 1.3.11

In this version:

• A 'tcpflags' option has been added to entries in /etc/shorewall/interfaces. This option causes Shorewall to make a set of sanity check on TCP packet header flags.
• It is now allowed to use 'all' in the SOURCE or DEST column in a rule. When used, 'all' must appear by itself (in may not be qualified) and it does not enable intra-zone traffic. For example, the rule
  
      ACCEPT loc all tcp 80
  
  does not enable http traffic from 'loc' to 'loc'.
• Shorewall's use of the 'echo' command is now compatible with bash clones such as ash and dash.
• fw->fw policies now generate a startup error. fw->fw rules generate a warning and are ignored

11/14/2002 - Shorewall Documentation in PDF Format

Juraj Ontkanin has produced a PDF containing the Shorewall 1.3.10 documenation. the PDF may be downloaded from

11/09/2002 - Shorewall is Back at SourceForge

The main Shorewall web site is now at SourceForge at http://shorewall.sf.net.

11/09/2002 - Shorewall 1.3.10

In this version:

• You may now define the contents of a zone dynamically with the "shorewall add" and "shorewall delete" commands. These commands are expected to be used primarily within FreeS/Wan updown scripts.
• Shorewall can now do MAC verification on ethernet segments. You can specify the set of allowed MAC addresses on the segment and you can optionally tie each MAC address to one or more IP addresses.
• PPTP Servers and Clients running on the firewall system may now be defined in the /etc/shorewall/tunnels file.
• A new 'ipsecnat' tunnel type is supported for use when the remote IPSEC endpoint is behind a NAT gateway.
• The PATH used by Shorewall may now be specified in /etc/shorewall/shorewall.conf.
• The main firewall script is now /usr/lib/shorewall/firewall. The script in /etc/init.d/shorewall is very small and uses /sbin/shorewall to do the real work. This change makes custom distributions such as for Debian and for Gentoo easier to manage since it is /etc/init.d/shorewall that tends to have distribution-dependent code.

10/10/2002 - Debian 1.3.9b Packages Available

Apt-get sources listed at http://security.dsi.unimi.it/~lorenzo/debian.html.

10/9/2002 - Shorewall 1.3.9b

9/30/2002 - Shorewall 1.3.9a

9/30/2002 - TUNNELS Broken in 1.3.9!!!

9/28/2002 - Shorewall 1.3.9

In this version:

• DNS Names are now allowed in Shorewall config files (although I recommend against using them).
• The connection SOURCE may now be qualified by both interface and IP address in a Shorewall rule.
• Shorewall startup is now disabled after initial installation until the file /etc/shorewall/startup_disabled is removed. This avoids nasty surprises at reboot for users who install Shorewall but don't configure it.
• The 'functions' and 'version' files and the 'firewall' symbolic link have been moved from /var/lib/shorewall to /usr/lib/shorewall to appease the LFS police at Debian.
