In general - the subscriber called - started picking. Replaced the abnormal activity of the pruter at port 23 .. Okay. I screwed all the service ports of the microbe on the firewalls on the brasses.
Day went to the subscriber. Reset the router. Otherwise, he was dumped somehow sooo tight.
He scored the settings and locked all the services .. In the evening, a panic at the abon. Remote access show strange!
Situation - Mikrotik remembered the IP address given 2 connections back !!!!! and began to arrange a robust DDOS from an already released address, natting his current session !!!!!!
Someone came across this ..
Microtik says that the firmware is "up to date"
