I know that this isn't a problem as I have no firewalling between the
two boxes in question.

I have just tested this with another server I had handy which basically
has the same config file except for the actual name servers it uses.

And it correctly reports itself as a Stratum three server (It's using a
couple of stratum two servers to sync against.)
