Where is that MARK coming from? Openswan has "taken" the hight bit to mean "This
mark is an SAref". If smoothwall is using it for something else, we have a problem.

That would only be if you have protostack=mast in your config. The default
protostack (=auto) tries netkey first, then klips.

In 2.6.29rc1 and onwards, you can use "ipsec policy" to get an "eroute like"

Are you confusing DESTDIR with FINALDESTDIR? The first is the physical location,
eg ~/BUILD/openswan/usr/lib/ipsec/pluto while the latter is the location of the file after
the package install, on the live system, eg /usr/lib/ipsec/pluto
