I just see wans as each location increasing the potential to backdoor the
server.
(like corporate data center location can be tight but the remote location
has
backdoor dialup or broadband users into their remote lan, connected to the
wan).
Your remote sites need to be as tight as the corp home location, but common
practice is often not.
