2.6.29 is the second-latest untested in GenToo. 2.6.31 the latest
untested. 2.6.31 crashes though if a connection is initiated so I had to
revert to 2.6.29 .

Using this Windows Agile VPN thing or how it is called hence pure IPSec
without l2tp. Used guides to set it up including a strongswan based one
which should be equal for the windows side. On the openswan side I use
the same conn I use for connecting using Un*x machines. Anything
particular one has to do there to get it working?
