Hmmz the fact is that the IP_QUERYING_SERVER is the random ip which connects to the server or sends a query for it. Hmmz mayby the problem is with my router that the provider said me to use GATEWAY_IP as my gateway but redirects it to the another ip NEW_GATEWAY_ADDRESS, mayby if i'll use that new gateways ip, it will stop that messages? But in that case i think i wont have the internet connection in my server anymore?
