Using mac os? Block the undisclosed spotify p2p broadcast udp traffic here!

[thefirewallking]

Undiscolosed spotify p2p traffic was leaking across my VPN connection to my employer. Thanks spotify!

On mac os high sierra, you can block this with:

$ sudo vi /etc/pf.conf

Add the following line to the bottom of the file:

block drop quick on <interface> proto udp from any to any port = 57621

Where <interface> is the interface over which the traffic is leaking

Then, disable/enable the firewall

$ sudo pfctl -d && sudo pfctl -e

Kind of annoyed that a premium subscription lends you to something you can't readily opt-out of.
