No problem.  If you are by any chance using FreeS/WAN (or one of its
derivatives) you have to setup 4 tunnel connections.  Subnet-to-Subnet,
Subnet-to-Host, Host-to-Subnet, and Host-to-Host.  There are e-mails in
the FreeS/WAN archives that show how to setup routes in order to
accomplish the same thing, but I like being able to see the actual
tunnels up and know what connections I've defined.  I.e., ipsec eroute
will let you see all 4 tunnels, not just 1 and you have to know that
routes are in place to allow traffic to flow in all 4 directions.
