Security, VPN access issues on TP-Link File Sharing [on hold]

If I attach a USB, or a Seagate drive to my router, here is some questions:

  • Does security is an issue to TP-Link router file sharing? is it better on security to monitor files on a file server (Computer)?
    • And is there any method for user to remote access the file sharing from the outside of the LAN? like from internet. Using VPN?
