Passive Port Change Issue

...On looking at the logs and traffic on Filezilla I could see there was an additional port request for 22021 from them. As the Readynas was only on 10021 and the passive were set to a higher range this could not be answered. Thats my logic behind it. So I tried then to change the Passive FTP ports to 22021 but I cannot use that port on there? This is now where I'm at with it.

The passive port numbers are sent over the control connection (10021 in your case), and the clients then try to create a connection back to the NAS using that passive port. If there is a firewall in front of the NAS, then the passive ports you pick need to be forwarded through that firewall. If not, then any passive ports will work. There's no reason why the passive ports need to have higher numbers than the control port.

So are these clients on the same network as the RN104, or are they connected over the internet.
