Re: Google Classroom Video not making it through firewall

Hello Matt,

Thank you so much for your reply. Unfortunately when I perform the 
'shorewall clear' command, I lose all access to the outside world 
(internet) so I am unable to test.

Thank you for your time.

Harold

When I replace PC#1 with PC#2, the video that is generated locally does not make it to the teacher. The teacher sees a blank screen. My child is able to see video received from the teacher. Audio continues to behave normally, that is the teacher and my child are able to communicate verbally.
