You can use Service dependencies to accomodate this scenario.

You'd want to add the intermediate router to your 3rd party hosted Nagios 
and then make the target routers dependent on the intermediate.

Or, you could bump up the RTT requirements to the target routers and treat 
the network in between as a slow black box.
