Peaty; I see your post is about a month old but if you still have the 895L and would like to gain access to your usb drive over the web here is what you do. Plug in your usb drive to one of the usb ports. You will then go to the share port tab under settings and enable DLNA Server, Windows File Sharing, and Web File Access......if you look under the Web File access it will list a couple of direct links for you to gain access while you're on your local network.....another thing you can do is download the share port app for your smartphone or tablet and just set it up by putting in your router's sign in and password........if you wish to gain access over the internet and use a web browser to view your usb contents while you're away from home you will need to go to the features tab and select Dynamic DDNS; you will need to go and set up DDNS through an external website which is https://www.dlinkddns.com ......you will set up a free account and set up a domain name that you will use so that you don't have to input your WAN IP address in because if your router reboots the WAN address changes (unless you have a static IP address) so thats the purpose of setting up this DDNS so that you can use this one address to gain access to your usb contents and access your router's GUI while away from home as well. Once you set up your DDNS on the website that I just gave you , go back to your router and go back to Dynamic DDNS and input all of the information that you just set up and make sure you use dyndns.com as your server address.....once you input all of that information click on save........then when you're away from home and want to view your usb contents via a web browser you would put in http, a colon,two forward slashes,your domain name, another colon, and port 8181......for example http:// johndoe:8181 you will then see the share port web box and you will then need to input your username and password of your router; by default the user name is usually admin...........let us know if that works for you or if you need any more help......I use this feature every day and it works just fine.....there wasn't a lot of documentation on how to configure this but that's how you do it......good luck!
