Shorewall Errata

IMPORTANT

-
    -
  1. -

    If you use a Windows system to download -a corrected script, be sure to run the script through dos2unix after you have moved -it -to your Linux system.

    -
    2. -
  2. -

    If you are installing Shorewall for the first -time and plan to use the .tgz and install.sh script, you can untar the -archive, replace the 'firewall' script in the untarred directory with -the one you downloaded below, and then run install.sh.

    -
    3. -
  3. -

    When the instructions say to install a -corrected firewall script in /usr/share/shorewall/firewall, you may -rename the existing file before copying in the new file.

    -
    4. -
  4. -

    DO NOT INSTALL CORRECTED -COMPONENTS ON A RELEASE EARLIER THAN THE ONE THAT THEY ARE LISTED UNDER -BELOW. For example, do NOT install the 1.3.9a firewall script if you -are -running 1.3.7c.

Upgrade Issues

The upgrade issues have moved to a separate page.

Problem -with iptables version 1.2.3

-
-

There are a couple of serious bugs in iptables 1.2.3 -that prevent it from working with Shorewall. Regrettably, RedHat -released this buggy iptables in RedHat 7.2. 

-

I have built a -corrected 1.2.3 rpm which you can download here  and I have -also -built an -iptables-1.2.4 rpm which you can download here. If you are -currently -running RedHat 7.1, you can install either of these RPMs before - you -upgrade to RedHat 7.2.

-

Update 11/9/2001: RedHat -has released an iptables-1.2.4 RPM of their own which you can download -from http://www.redhat.com/support/errata/RHSA-2001-144.html.I -have installed this RPM on my firewall and it works fine.

-

If you would like to patch iptables 1.2.3 yourself, -the patches are available for download. This patch -which corrects a problem with parsing of the --log-level specification -while this patch -corrects a problem in handling the  TOS target.

-

To install one of the above patches:

Problems with kernels >= 2.4.18 and RedHat -iptables

-
-

Users who use RedHat iptables RPMs and who upgrade to kernel -2.4.18/19 may experience the following:

-
- 
# shorewall start
Processing /etc/shorewall/shorewall.conf ...
Processing /etc/shorewall/params ...

iptables: libiptc/libip4tc.c:380: do_check: Assertion
`h->info.valid_hooks == (1 << 0 | 1 << 3)' failed.
Aborted (core dumped)
-
-

The RedHat iptables RPM is compiled with debugging enabled but the -user-space debugging code was not updated to reflect recent changes in -the Netfilter 'mangle' table. You can correct the problem by installing - -this iptables RPM. If you are already running a 1.2.5 version of -iptables, you will need to specify the --oldpackage option to rpm -(e.g., "iptables -Uvh --oldpackage iptables-1.2.5-1.i386.rpm").

-

Problems installing/upgrading RPM on SuSE

-

If you find that rpm complains about a conflict with kernel <= -2.2 yet you have a 2.4 kernel installed, simply use the "--nodeps" -option to rpm.

-

Installing: rpm -ivh --nodeps <shorewall rpm>

-

Upgrading: rpm -Uvh --nodeps <shorewall rpm>

-

Problems with iptables version 1.2.7 and -MULTIPORT=Yes

-

The iptables 1.2.7 release of iptables has made an incompatible -change to the syntax used to specify multiport match rules; as a -consequence, if you install iptables 1.2.7 you must be running -Shorewall -1.3.7a or later or:

- -

Problems with RH Kernel 2.4.18-10 and NAT
-

-/etc/shorewall/nat entries of the following form will result in -Shorewall being unable to start:
-
-
#EXTERNAL       INTERFACE       INTERNAL        ALL INTERFACES          LOCAL
192.0.2.22      eth0            192.168.9.22    yes                     yes
#LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE
-Error message is:
-
Setting up NAT...
iptables: Invalid argument
Terminated

-The solution is to put "no" in the LOCAL column. Kernel support for -LOCAL=yes has never worked properly and 2.4.18-10 has disabled it. The -2.4.19 kernel contains corrected support under a new kernel -configuraiton option; see http://www.shorewall.net/Documentation.htm#NAT
-
-

Problems with RH Kernels after 2.4.20-9 -and -REJECT (also applies to 2.4.21-RC1)

-Beginning with errata kernel 2.4.20-13.9, "REJECT --reject-with -tcp-reset" is broken. The symptom most commonly seen is that REJECT -rules act just like DROP rules when dealing with TCP. A kernel patch -and -precompiled modules to fix this problem are available at ftp://ftp1.shorewall.net/pub/shorewall/errata/kernel.
