Hi,
I tried posting this to FreeBSD-questions and to freebsd-security (while not
a member) and haven't had any replies.
I'm trying to get IPsec running between 2 FreeBSD boxes, using racoon2.
I was originnaly using vmware systems, but in order to eliminate vmware as a
cause, I've moved it to a native machine.
spmd and iked start up okay, but I get an error when I try a ping across the
tunnel.
/var/log/messages shows:
May 5 13:52:36 biosa-vm4 iked: [INTERNAL_ERR]: if_spmd.c:726: SLID failed:
550 Operation failed
May 5 13:52:36 biosa-vm4 iked: [INTERNAL_ERR]:

172.20.36.52[0]:0x0:can't find selector (index (null))
The startup shows:

Without IPsec running, I can ping the remote interfaces 192.168.[14].1 both
ways
My racoon2.conf looks like:

CERTDIR "/usr/local/etc/racoon2/cert";
};
