This can not be true. Either the DHCP server is remote or in the same
subnet. But it can not be both. (Unless you got a L2 bridge in there.)
Perhaps you ment to say something differently which I did not understand?

Sounds like a perfect place for DHCP relaying. But your nagios server must
be in the same network as the other clients if you want a meaningfull
result.

If it is not in the same network you may get a lease from the server while
the stations on the other network may not get one because your pool for
that network is exhausted.

This is not a plugin limitation but actually how DHCP works.
