Find "Share Large Files over the Internet" on page 45 at link.
I want to replace my Netgear R4500 with a new router that has a USB port for an external hard drive, and the functionality that allows my geographically distant family members to see the photos and videos I store on that external hard drive by using their own internet browser functionality. The Netgear R4500 does have a USB port that can connect to an external hard drive, but the contents are accessible only to my home network devices, not to the outside world. I do not need the functionality of a commercial server, such as an NAS, just the ability to share content over the internet with my spread-out family. I have used Dropbox, but that does not meet my wishes. Price of a new router matters some, but not nearly as much as simplicity to setup and use.
