Hi there,

a pretty strange problem with Kerio Control 9.2.1:

yesterday i upgraded my Nexus5 Android Device to Android 7.1.1 (LineageOS).
The Device is connected via WIFI to Kerio Control.

The Problem:

about 30 seconds after connecting to WIFI, the Device does only get email notifications from gmail, no other apps are able to notify (google hangouts, WhatsAPP, Pushover, and so on)


so i was researching:

- first i connected my phone to another wifi hotspot (without KC) -> everything works
- Connecting back to KC -> same problem again
- disabling all security features of KC -> same problem
- changing DNS server on phone to google DNS (also tried with different DNS servers) -> it works
- enabling all security features of KC -> still works
- changing DNS back to KC DNS -> failed again
- trying some different settings in KC DNS -> same problem


So the fix is: change the dns on the phone to an external DNS, but that could not be normal.

the only thing i have not tested was the transparent proxy - maybe this is the problem?

So, is there any other "feature" which could be the problem?
Is it a bug?


a colleague of mine, has the same problem in his office with OnePlus One, they also use KC.
