Telling whether session on RDP Server is remote or not

Hello Everyone,


I need to be able to tell if a session (RDP) on a server is a remote
session or not.
I need to be able to tell if the machine which the user is RDPing from
is from inside the firewall or not.

So - if I was able to get the IP Address of the remote client that would
be great.  But I am not sure how to go about this.

Any thoughts as to how I might accomplish this?
