Hello,

I installed TP-Link Tapo C200 Security camera in my LAN network. The camera itself is working fine and connections through TP-Link cloud is working ok.

When I was looking for my Firewall logs from my Internet access router, I can see that Tapo camera is continuously trying to connect Amazon cloud in Ireland with UDP traffic and the answers are blocked. The log file is full of sequences like this:

Sessions from the TP-Link cam to Amazon (traffic goes through the Firewall to Amazon):
UDP: tapo.cam.LANip.address:19381 -> 54.228.218.124:3478
UDP: tapo.cam.LANip.address:19382 -> 54.48.246.100:3478
UDP: tapo.cam.LANip.address:19381 -> 54.48.246.100:3478

Returning traffic (traffic is blocked in my Firewall):
UDP: 52.48.246.100:3479 -> my.firewall.ip.address:19382
UDP: 52.229.218.124:3478 -> my.firewall.ip.address:19382

Don't know really what this traffic is and I don't assume it is any kind of security issue. Happens once in 5 minutes or so. The IP and port numbers in the returning traffic does not seem to match. Difficult to believe, Amazon was having issues in their cloud either, so I'm a little empty handed here. 

Any idea from anyone?

Regards
Kelmi
