@ -2203,11 +2203,12 @@ We have an error talking to the kernel
<para><emphasis role="bold">Answer:</emphasis> Shorewall implements a
stateful firewall which requires connection tracking be present in
ip6tables and in the kernel. Kernel's before 2.6.20 didn't have
ip6tables and in the kernel. Linux kernel's before 2.6.20 didn't have
connection tracking for IPv6. So we could not even start to develop
IPv6 support until then. By the time that distributions began shipping
with kernels that supported IPv6 connection tracking, they were
shipping with 2.6.25. So that is what we developed IPv6 support on and
IPv6 support until 2.6.20. We understand that there were significant
problems with the facility until at least kernel 2.6.23. When
distributions began offering IPv6 connection tracking support, it was
with kernel 2.6.25. So that is what we developed IPv6 support on and
that's all that it has been tested on. If you are running 2.6.20 or
later, you can <emphasis role="bold">try</emphasis> to run Shorewall6
