Hi
My first post here so bear with me!
I have been in contact with our account manager at LogMeIn to discuss this issue at length. We are working for a way to overcome this but our responses from LGFL has been minimal.
It should be noted that Serco Learning have not changed any of our remote access policies - and we were as caught blindsided by this as you were. I would advise all schools to discuss this with your ISP and we will continue to work on a technical solution with our Partner from LogMeIn.
