Network PORT specs? - csfuser - 04-26-2020

I'm new to JK, but no stranger to networking, remote apps, etc.
I've done some research on the interweb and forums, and I know the team is buried with all the recent activity, but...

Can someone from the JK team please "sticky" which ports [UDP/TCP] are used by the JK client(s) so I can open them on my firewall?

I won't arbitrarily open up UPNP on my network for security reasons. 
I'd prefer to implement port forwarding firewall rules to specific local client IP's, so I need to know which ports to forward!
I see 12000-12010 on other threads...  are these still correct?

Viewing active TCP ports I see:
JK using UDP 56192 - 62337 local
JK using TCP 6767 remote to nodebalancer!
It's also uses http/https calls to AWS and other "sites"..


I have a fast 300/50 (mbps) connection, yet most of the JK clients in sessions show as poor, fair or unacceptable. 
I have a public IP from ISP, and IPv6 is NOT enabled on my network!

I'd like to explore the app potential, but "no audio" and poor connection quality (again, assuming due to blocked ports on the firewall) are not helping.

Pls advise, and THANKS in advance.

Search here for - router - network - port forwarding - firewall

And - no audio - grayed out and so on

"General loose tips - if technical problems in sessions; "NO AUDIO" und so weiter:

Author unknown - maybe or probably Eric McQuaid:
"the person seeing no audio usually has a router not letting audio in"

Try RESYNC-button
Try leave session - and come back
Maybe restart JamKazam
- and computer
- and router"

ROUTER SETTINGS - old, but still valid, I think

No need for 'sticky' anything.
You can determine yourself which ports are used by jkz by simply configuring them in the network section of the app/program. (at least 5 consecutive - UDP) 
Since you know about networking, just look at the ports jkz 'reserves' after startup and 'lock' those in the config. Then forward them in your router to the wired NIC on your machine running jkz. Basically you can pick any range to your liking as long as you stay 'out of the way' of the well know and much used numbers.

NB - on a well configured network with clean and monitored machines, UPnP is actually more secure than permanent forwarded/open ports.

Hans,
thanks for your reply.. Some good info in those links...

Would you have any advice as to what if any advantage there is switching JamKazam from using IPv6 to IPv4 with port forwarding?  I just watched a video tutorial (https://www.youtube.com/watch?v=R0xKMsINU1M&t=245s) where at the beginning, they switched the IPv6 off, and went with IPv4 and port forwarding to 12000 to 12010.

My system is working ok, but, unless musicians are fairly close by, the overall latency is a killer, so, I'm just wondering if this might help?

Scott.. I simply have IPV6 turned off on my network... I'd be interested to see what advantages there might be to having IPV6 on - other than not being able to connect to others who are IPV6 only!
