Linkstation LS-CH2 setup problem

[fairwood]

I'm currently using WZR-HP-G300NH flashed with dd-wrt firmware 

 

I want to setup a FTP which allows me to access to the NAS 

 

should I goto service > NAS for the setup 

or goto NAT/QoS > port forward for the setup 

 

I've tried both but couldn't work. can any me teach me how to setup 

 

Thank you

NAT/QOS and forward port 21 to the ip of the linkstation, make sure you have FTP enabled on the shared folder options and that you have the FTP service itself enabled.
