Thanks Mr. Aleksandar for your input on this one.
This is indeed my setup for the testbed used for the two previous
reports and all the upcoming ones.
To help Mr. Yongang with his setup, and anybody else trying to set
this up, I plan to post a mini-report (Report 0) to lay down the
instructions for setting up a system similar to the one used in the
reports.

Best regards,
