SSDP (UDP 1900) over L2TP VPN Connection
I wish to control my Sonos audio system remotely via iPhone.
I've configured and successfully connected to my Astaro via L2TP over IPSec. The iPhone is assigned 192.168.0.2 address from custom VPN Pool. This is the same subnet as my local home network on which the Sonos boxes reside.
I am able to ping my Sonos boxes from the iPhone when connected via VPN.
The Sonos app uses SSDP (UDP port 1900) to destination 184.108.40.206 (broadcast) to detect the Sonos boxes.
I ran Wireshark on my local network and was not able to see any SSDP traffic from the iPhone.
Thus, my question is, what is preventing SSDP packets originating from my iPhone from reaching my local network?
