I was referred here by Nest Cam support. Our clients are using a Sophos UTM firewall with a transparent HTTP proxy. The proxy does not understand the traffic being sent to hosts like oculusYYYus1.dropcam.com,
The main issue seems to be viewing the camera feed when behind the same firewall vs. externally. The camera feeds leave the network just fine, viewing behind the proxy is where issues crop up.
We have to whitelist these but found that they change sometimes. Is there a static list of IP addresses or host names we can proactively whitelist? Maybe a block of addresses or a DNS record that includes them?
