How to configure ports for firewall access??

I have an app on my network being blocked by Avast One firewall. The app manufacturer (Sonos) provides info on specific ports that need to be open for it to work. I am unable to find settings in the Avast client to configure these ports. A chat session with Avast tech support was maddeningly unproductive. Can anyone tell me where to find this?

Hi, set the Avast Firewall to private/trusted mode/network and reboot.

Thanks Asyn,

Only option I have there is “trusted”, and it’s been on that setting all along.

I’m starting to get the bad feeling that the Avast One client doesn’t support configuring individual ports… That would be bad. I have confirmed that when I shut the firewall off the Sonos app works fine.

You’re welcome.

I could help you with APS - but no (further) ideas regarding A1, sorry.
