How to allow the traffic to specific IP that Sophos is blocking

Could that be whats app traffic? that's what I'm getting when doing a generic lookup for that IP. 

Do you have any web protection turned on? maybe uncheck Enable pharming protection. PROTECT > WEB > GENERAL SETTINGS > expand advanced.

Tried it, didn't helped. Still seeing denied packages in the log viewer.

Those packets do not indicate any problem at all.

I advice customers to disable the logging of Invalid Traffic, because it does not grant useful insights in traffic. 

The main question is: Do you have any issues in your network or only does packets? 

If only logging is the main concern, disable the logging.

Hey. Yes, i got some problems. This is outside network, in which i want to connect. 

Which application causes the issue? What is the network flow? 

Because if you log invalid traffic, it most likely means, the application could connect but disconnect for what ever reason. Could be related to the application or could be related to outside network.

RST means, there was a connection and your Client or the Server sends a Reset to kill the connection. 

Hey. There is connection i think, as i can ping that ip from the diagnostics tab. The problem is that GRE protocol is not passing .

You should look at the tcpdump level and try to understand, what is the problem.
