I absolutely see no reason the camera ping a site in china every 30 seconds. Keep alive is important for your service, but why not use a wyze server for it, than Chinese servers or even google.com?
I want to set my firewall to allow what is needed and not having this cameras unchecked going to places.
Mask it how. Not sure my dinky little router can do that.
I run my own DNS server with blocking and I blocked both cm and gm connections, so the device switched to google.com. It pinged it about 5k times just in the past 11 hours.
OpenDNS works like a charm. I use it to block cm.iotcplatform.com (the Chinese one). Between the filter categories and custom blocking options it gives excellent control. iotcplatform.com is part of ThroughTek and is the service used by Wyze for NAT punching.
