I second Bernhard's suggestion - use OpenVPN, unless you have a specific
reason to use IPsec.  There's a package of OpenVPN for Owl in our
contrib directory - but it lacks compression support.  For compression,
you will need LZO.  To build LZO from source, you will need NASM - it's
available in our contrib directory.  So if you like to install all of
this stuff with RPMs, you seem to have these options:

- try the OpenVPN package from contrib/ - but you don't get compression;

- install binary RPMs from a compatible version of Fedora (FC3 or FC4
for Owl 2.0);

- install the NASM package from our contrib, rebuild LZO from Fedora,
then rebuild and install OpenVPN (from our contrib, from, or
from Fedora);

- same as above, but use the binary package of NASM from Fedora (their
source package of NASM has extra dependencies, if I recall correctly);

- rebuild Fedora packages, matching and rebuilding all dependencies (you
could be forced to rebuild a lot of them).

When I was installing this stuff a year ago, we did not yet have the
contrib packages.  Here are the package versions that I happen to have
installed on an Owl box with OpenVPN:

nasm-0.98.39-3 (Fedora binary RPM)
lzo-1.08-6, lzo-devel-1.08-6 (rebuilt from Fedora)
openvpn-2.0.7-1 (rebuilt from a download)

I hope this helps.
