Everything is working exactly as I want now, thanks for the info, it was what I needed. Some updates to the steps in case someone comes across this thread later.

  1. Directly connect your computer to the LAN port
  2. Login to the router
  3. Connect to your existing network to the WAN port
  4. Connect the external usb drive, use NTFS or EXT format for your HDD.
  5. Turn off wifi
  6. Make the drive writable (Applications->File Sharing-> turn Writable on)
  7. Put the router at AP mode (more settings ->network mode)
  8. Unplug your computer from the LAN port and move the network connection from WAN to LAN.
  9. Set up static IP (e.g. 192.168.1.100) to it in your main (existing) router, supposing it should have this function. Otherwise you can just find out the IP address of the mini router if it works as DHCP client.
  10. Finally you can access your HDD in File Explorer using the IP. ie: //192.168.1.100/

Thanks again, little box is a good solution for this.
