I got the same trouble as the following link: http://msgs.securepoint.com/cgi-bin/get/linux-ipsec-0207/365/1.html Using the gentoo-sources for my kernel on Saturday the 21st September Bertrand
try lolo_sources-2.4.19.10_pre3 if you have the time... I switched to a release version of ipsec which hopefully should fix a bunch of problems people were having... with a little luck they will get their 2.0 out the door soon and we'll all be able to benefit from that...
