In that case, I'm interested to see the openswan logs (without plutodebug= or
klipsdebug), and the xl2tpd logs (please recompile with the debug flags
specified as illustrated in the Makefile).

Which versions of xl2tpd and openswan are you using? Can you try openswan
2.4.x CVS and xl2tpd GIT?

I will release xl2tpd 1.1.07 today, but I can't release openswan-2.4.8 yet
without fixing the 2.6.19/2.6.20 crashers, so for that you should probably
try the CVS version.
