Bonjour,

I currently run MC 20.0.131 on Windows 7 on a Lenovo Laptop T530.

Recently, I get a message from the Norton Firewall that JRiver MC 20 wants to reach an Internet address via UDP Port 1900 and this is considered suspect by Norton. The Norton pop up message recommends to block this - which I do everytime I boot.

I use JRiver on my LAN only. What is this UDP connection for? It is initiated by JRiver?   

Regards

Norton should know better.  It's used for UPnP and perfectly normal.

Try a Google search for "port 1900" to learn more.

JimH, thank you.

I did research UDP port 1900 and now I understand what it is. I will configure Norton to allow this UPnP traffic to go on in the future.

Strictly speaking your router should be set up to block UDP multicasts between your LAN and the WAN (so that you cannot search the world for UPnP devices (bad), and so that the world cannot search for your UPnP devices (worse)). However that is a function that you would set on your router, and totally unrelated to Norton.

And on the other hand Norton should be allowing all UPnP traffic within your LAN without hindrance.
