To install Shorewall using the RPM:

If you have RedHat 7.2 and are running iptables version 1.2.3 (at a shell prompt, type "/sbin/iptables --version"), you must upgrade to version 1.2.4 either from the RedHat update site or from the Shorewall Errata page before attempting to start Shorewall.

Install the RPM (rpm -ivh <shorewall rpm>).

Note: Some SuSE users have encountered a problem whereby rpm reports a conflict with kernel <= 2.2 even though a 2.4 kernel is installed. If this happens, simply use the --nodeps option to rpm (rpm -ivh --nodeps <shorewall rpm>).
Edit the configuration files to match your configuration. WARNING - YOU CAN NOT SIMPLY INSTALL THE RPM AND ISSUE A "shorewall start" COMMAND. SOME CONFIGURATION IS REQUIRED BEFORE THE FIREWALL WILL START. IF YOU ISSUE A "start" COMMAND AND THE FIREWALL FAILS TO START, YOUR SYSTEM WILL NO LONGER ACCEPT ANY NETWORK TRAFFIC. IF THIS HAPPENS, ISSUE A "shorewall clear" COMMAND TO RESTORE NETWORK CONNECTIVITY.
Start the firewall by typing "shorewall start"

To install Shorewall using the tarball and install script:

unpack the tarball (tar -zxf shorewall-x.y.z.tgz).
cd to the shorewall directory (the version is encoded in the directory name as in "shorewall-1.1.10").
If you are using Caldera, RedHat, Mandrake, Corel, Slackware or Debian then type "./install.sh"
If you are using SuSe then type "./install.sh /etc/init.d"
If your distribution has directory /etc/rc.d/init.d or /etc/init.d then type "./install.sh"
For other distributions, determine where your distribution installs init scripts and type "./install.sh <init script directory>
Edit the configuration files to match your configuration.
Start the firewall by typing "shorewall start"
If the install script was unable to configure Shorewall to be started automatically at boot, see these instructions.

To install my version of Shorewall on a fresh Bering disk, simply replace the "shorwall.lrp" file on the image with the file that you downloaded. See the two-interface QuickStart Guide for information about further steps required.

If you already have the Shorewall RPM installed and are upgrading to a new version:

If you are upgrading from a 1.2 version of Shorewall to a 1.4 version or and you have entries in the /etc/shorewall/hosts file then please check your /etc/shorewall/interfaces file to be sure that it contains an entry for each interface mentioned in the hosts file. Also, there are certain 1.2 rule forms that are no longer supported under 1.4 (you must use the new 1.4 syntax). See the upgrade issues for details.

Upgrade the RPM (rpm -Uvh <shorewall rpm file>) Note: If you are installing version 1.2.0 and have one of the 1.2.0 Beta RPMs installed, you must use the "--oldpackage" option to rpm (e.g., "rpm -Uvh --oldpackage shorewall-1.2-0.noarch.rpm").
Note: Some SuSE users have encountered a problem whereby rpm reports a conflict with kernel <= 2.2 even though a 2.4 kernel is installed. If this happens, simply use the --nodeps option to rpm (rpm -Uvh --nodeps <shorewall rpm>).
See if there are any incompatibilities between your configuration and the new Shorewall version and correct as necessary.
Restart the firewall (shorewall restart).

If you already have Shorewall installed and are upgrading to a new version using the tarball:

If you are upgrading from a 1.2 version of Shorewall to a 1.4 version and you have entries in the /etc/shorewall/hosts file then please check your /etc/shorewall/interfaces file to be sure that it contains an entry for each interface mentioned in the hosts file. Also, there are certain 1.2 rule forms that are no longer supported under 1.4 (you must use the new 1.4 syntax). See the upgrade issues for details.

unpack the tarball (tar -zxf shorewall-x.y.z.tgz).
cd to the shorewall directory (the version is encoded in the directory name as in "shorewall-3.0.1").
If you are using Caldera, RedHat, Mandrake, Corel, Slackware or Debian then type "./install.sh"
If you are using SuSe then type "./install.sh /etc/init.d"
If your distribution has directory /etc/rc.d/init.d or /etc/init.d then type "./install.sh"
For other distributions, determine where your distribution installs init scripts and type "./install.sh <init script directory>
Check your configuration for incompatibility with 1.4 as described above.
Restart the firewall by typing "shorewall restart"

If you already have a running Bering installation and wish to upgrade to a later version of Shorewall:

Configuring Shorewall

You will need to edit some or all of the configuration files to match your setup. In most cases, the Shorewall QuickStart Guides contain all of the information you need.
