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

through firewall

Hello,
My name is Harold. I use a dedicated PC to provide IP Forwarding, DHCPD and
Firewall services for my home. All communications with the outside world go
through this PC. Lets call this PC#1. PC#1 has Slackware 14.2 x64 installed on
it with all of the latest updates. I have a second PC, identical hardware as
PC#1, that has Slackware 15.0 x64 installed on it again with all of the latest
updates. Lets call this PC#2.
My child uses Google Classroom to participate in on-line school. With PC#1
connected to my network, normal two-way video and audio communications between
the teacher and my child are possible. 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.
For PC#1 and PC#2 I am able to use identical initialization scripts, except for
rc.inet1.conf which has updated formatting on PC#2. For the Firewall services,
I utilize Shorewall with the same scripts for both PC's.
FaceTime between a couple of ipads works just fine.
I've provided shorewall dumps for both PC's. If I could get some insight as to
how to log the interaction that is not working, I would greatly appreciate it.
Thank you for your time!
The only thing that I can help you with is to isolate if this is a Shorewall
issue.
If you do 'shorewall clear' on PC number two, does it work properly?
