TCP/IP connection on HXF300

Hi Gurux hope you're doing.
i need your guidance, i'm trying to gain access to my meter remotely over tcp/Ip by using the DLMSDirector .
i know all required parameters and security that i already use in local mode .
i have selected the NET " media" and put the IP address "Host name" and port of my meter.
but the meter didnt reply, of course we are in the same network . It would great if you give us a little help . thanks in advance.
