Last I knew, 5.2.1 still had broken IPsec. Specifically, the system
tries to apply the IPsec policy to the IKE traffic giving us a chicken
and egg problem. The Mac end timing out waiting to hear from the
FreeBSD system is consistent with this. Run 'tcpdump -n port 500' on
the FreeBSD system and watch for outgoing traffic, and have a look at
'netstat -sp ipsec' and see if the 'outbound packets with no SA
available' count is increasing.

The workaround was to not use IPSEC in the kernel, but FAST_IPSEC.
