Note that ESP and TUNNEL support got split into ipv4 and ipv6 versions, so if
this was an ipv6 version, you would also need:
If using compress=yes, you would also need:
and you would need to modprobe the corresponding modules if you are not
using the openswan startup scripts.
However, all of this does not seem to be your problem though it would not
hurt to verify with ipv6 enabled as module just so we can rule this out.
It might be useful to see "ipsec verify" and "ipsec barf" to get more info
about your system state.
