Test out the connection. ‘Cause as we all know, it will  “speeds up to 400/50” that I will be getting. Then Darkstat on the pfsense unit when we move the office over. Planning to go with Mark’s suggested iperf (Thank you Mark!) on a box I pull from the recycling shelf to test the connection while the space is being built out. Fingers crossed that will bring me fewer surprises and inform all parties as to the nature of our connection. 
Cheers for the advice.
