My Philips soundbar can be used in combination with the Spotify App (Spotify Connect) so everyone connected to the same network can get control over it and play their music.
The soundbar doesn't give me any options to control access so I want to change it with the router.

Using the command "iptables -I FORWARD 1 -d 192.168.x.x -j DROP" I can block access to the soundbar but (my question):

How can I allow traffic between a specific device (my pc and/or smartphone) and the soundbar and still have other devices trying to access blocked.

Please help me

Mike

The soundbar needs to be on another sub-net than the other devices for iptables to work.

iptables -I FORWARD 1 -s 192.168.y.y -d 192.168.x.x -j ACCEPT
iptables -I FORWARD 1 -d 192.168.x.x -j DROP
