By the way, just to rule out iptables I flushed all the additions made
in troubleshooting and the packets were still correctly routed.  The only
change necessary outside of the ipsec.conf was setting the proc ip_forward
value to 1.  Other than that, no marking etc.  Now maybe the marking etc
is necessary to get nat traversal working, I don't know.  And I have to get
nat traversal working as 90% of where the roadwarriors will be are going to
be behind NAT devices...
