Remote Desktop Connections

   Interesting, but it doesn't tell me what configuration you did for
the port forwarding.  As I said, you need to arrange for the target PC
always to get the same IP address.  Then you need to arrange to forward
external port <some_port> to port 3389 on the PC's address.  From home,
you need to tell the  Microsoft Remote Desktop client to connect to
<R8500_external_address>:<some_port> as the "PC name".

   It's generally best to use a different external port from the
well-known one (3389) for a service like Microsoft Remote Desktop.  Many
simple-minded attack programs try the well-known port, and quit if it
doesn't work.  Using a non-default port makes it harder to guess the
right port.

   Are you using more than one router?

   As an example, here's what I did for a test:

                          Service  External   Internal   Server
#   Service Name          Type     Ports      Ports      IP Address
16  win10 Remote Desktop  TCP/UDP  4389-4389  3389-3389  10.0.0.71

where my Windows target system was at 10.0.0.71:

   You're not going to make me drive all the way from Saint Paul, are
you?
