I have a synology router running my home network. And just yesterday it started blocking my wemo devices from accessing IP address 22.214.171.124 for security reasons.
Is this normal behavior for the devices, or did something change with them?
It is possible that the threat data bases that synology gathers may have been updated and now include this...

Hi, ScottChapman. Let us have a closer look at this. This is a bit odd. Are there other devices, aside from the Wemo that are also affected? Did you do anything to the router, like updating its firmware? Also, are the Wemo devices’ firmware are up-to-date?

Firmware on the router didn't update. The feature on the Synology router uses a bunch of external databases (including Google's) to determine what behavior is bad. I don't really know what the source is but I could perhaps contact Synology and see if they might be able to narrow that down.
However, you guys should know if that IP address is one you expect the switches to use in their normal behavior?

Yea, my router sets up clients to to use it as the DNS. WOuld the devices have gone directly to that on it's own?
Not experiencing any issue during that period of time.

Warning email from router was:
The connection from Wemo-Device1 to 4.2.2[.]2 has been blocked for security reasons(Malicious).
Sent from your Synology Router- HomeRouter
Searching for Synology and 126.96.36.199 I found this dated yesterday also:
Might Synology safe settings be blocking? Even if it were being blocked, 188.8.131.52 is nowhere in my network and should not be accessed by wemo. If I understand correctly, if one (recursive) DNS server doesn’t have the address of interest, it queries other DNS servers but it itself responds to the original request.

My Synology router has also begun blocking my Wemo from reaching 184.108.40.206.
How do I get my wemo to use the DNS that my router provides via DHCP?

Same here. Some WeMo devices are trying to connect to 220.127.116.11, but not all of them. I have 6 WeMo devices and only three of them trigger the block.
