FTPS security question

Hello guys,

finally i have my small nas setup complete at home and was thinking about some security issues regard FTPS service.

My intent is to acces from WAN to my ftp shared folder with a friend, now Ftp is reachable and works like a charm: my friend can correctly read and write on the shared folder with filezilla, my router is reachable with DDNS service and works perfectly.

Now I want to add more security, because now I had my ftp port opened on the router and I was wondering if FTPS is a good idea regarding this: i mean setting up a connection with TLS/SSL with FTPS is a good way to remove attacks from external connections? Or just a VPN is the right way to be prepared to attackers?

From my understanding i can setup a secure connection so just certificated user can get access to my ftp, but is that a good protection for router? Is it enough ?

Thanks to all of you guys!

Thanks a lot man!

In the end I discovered the SFTP plugin and i decided to use it with key login and higher port access, this sounds quite sure for now, not the best, but i suppose quite secured!

Thanks for support!
