Config Passive FTP port on TeraStation (TS-RVHL55A)

[hakivn]

Dear all
access to TeraStation over Internet ( via port forwarding on Modem), i have "500 Illegal PORT command" error after insert user name/password.
in fact, with the same user/password but login inside Local network, everything works well.
I think TeraStation need forward Passive FTP port ( other than port 21) but i can not find where to config Passive port range.
please help me how to config this port ranger.
Thank so much
P/s:  i can not forward all ip ranger.
