We have not done extensive testing of the configuration file parser,
and some of the scripts (of which some have been replaced by a new
library called libipsecconf) were not "ipv6 ready".

If you really want to test with IPv6, I suggest you try not using a
config file, but doing everything via "ipsec whack" commands. I am sorry
there is currently no better way.
