Hello.
I do as instructed.
http://wiki.mikrotik.com/wiki/User_Manager/DHCP_Example
The client connects, gets some in the user manager IP address, but the statistics in the User Manager is not considered. Why?
If possible, please reply in Russian 
What do you mean by “statistic is not considered”?
I wanted to say: not considered traffic from the connected client through UM. That is the volume in megabytes, and the session in seconds are always zero
to make traffic accounting you must use hotspot.
