Agent cascading

We have a centralized Dude server. This server connects to a Dude server on-site at our clients. We now have a client that has a routed network, that doesn’t allow direct connections to the endpoints from our external server. I can, however connect a Dude server near the end points to the main dude server at the HQ of the client. Is there a way to cascade this to our main server?

for example: Our Dude → Agent connect to Dude server at client’s HQ → agent connect to Dude server near the endpoints

This works:
Our Dude → Agent connect to Dude server at client’s HQ
Dude server at client’s HQ → agent connect to Dude server near the endpoints

But on our server I cannot see the agents registered through the Dude server at client’s HQ

Thanks!
