<P>The FreeS/WAN project needs you! We rely on the user community to keep
up to date. Mail users@lists.freeswan.org with your
interop success stories.</P>

<P><STRONG>Please note</STRONG>: Most of our interop examples feature 
Linux FreeS/WAN 1.x config files. You can convert them to 2.x files fairly 
easily with the patch in our

<P>Vanilla
FreeS/WAN implements <A HREF="compat.html#compat">these parts</A> of the
IPSec specifications. You can add more with 
<A HREF="http://www.freeswan.ca">Super FreeS/WAN</A>, 
but what we offer may be enough for many users.</P>
<UL>
<LI>
To use X.509 certificates with FreeS/WAN, you will need 
the <A HREF="http://www.strongsec.org/freeswan">X.509 patch</a> 
or <A HREF="http://www.freeswan.ca">Super FreeS/WAN</A>,
which includes that patch.</LI>
<LI>
To use 
<A HREF="glossary.html#NAT.gloss">Network Address Translation</A> 
(NAT) traversal
with FreeS/WAN, you will need Arkoon Network Security's
<A HREF="http://open-source.arkoon.net">NAT traversal patch</A>
or <A HREF="http://www.freeswan.ca">Super FreeS/WAN</A>, which includes it.
</LI>
</UL>


<P>We offer a set of proposals which is not user-adjustable, but covers
all combinations that we can offer.
FreeS/WAN always proposes triple DES encryption and
Perfect Forward Secrecy (PFS).
In addition, we propose Diffie Hellman groups 5 and 2 
(in that order), and MD5 and SHA-1 hashes.
