I don't have a problem with racoon (because I use MSIZE too), but I have
a problem with the actual data transfer over the encrypted tunnel, see
Message-Id: <20040805223027.7df0732b at Magellan.Leidinger.net>. If I use
FAST_IPSEC instead of IPSEC, everything works.

So you're able to transfer data over the tunnel with IPSEC?

It's a simple configuration, I've configured a gif tunnel between the
FreeBSD box and a hardware appliance (I've only access to the FreeBSD
system), added some SPD entries with setkey, configured racoon with a
pre-shared key and added a static route. With 4.10 this worked without
problems. After replacing the 4.10 box with a 5-current one, I had to
switch to FAST_IPSEC to get it working.


           I'm available to get hired (preferred in .lu).
