Ive got an audio-receiver which is connected per dhcp on green and it has access to the internet. Now I want it to control it with a app from mobile-phone connected on blue. The app didnt find the audio-device, but I can ping the device from my mobile.
Do I have to setup a additional Rule for it? And if yes, how?
Thank you and regards
Hi,
Do I have to setup a additional Rule for it? And if yes, how?
it depends. If that app relies on broadcasting to detect the audio-receiver, a firewall rule won’t
help as broadcast traffic is not emitted to other network zones.
Apart from that, please refer to the wiki for further information on how to create firewall
rules. Some recommendations from my humble self on building and maintaining firewall rules can be
retrieved here.
Thanks, and best regards,
