Roland, how do you handle customer requests regarding the remote management of 
their devices?
i.e. if the customer wants to do any kind of management (ssh, snmp) from 
outside his router, he must use our
infrastructure address (which is configured on his router) as a destination.
Generally, the customer might want to use this wan address for many other 
things which you shouldn't actually care,
since it's his router.

Why would the customer not have a loopback interface configured on his router with an accessible IP address? Relying on the WAN address is arguably a poor choice for a number of reasons including renumbering events and circuit outages.
