User Portal Introduction
Deployment
1.1 User Portal Introduction
The User Portal is a web-based portal, providing a collection of photos, videos, music, folders
and desktop links. This feature in NBG-510S provides secure remote access to the resources in
the LAN of the NBG-510S. All the connections to the Portal will be through SSL secured
communications. SSL topology encapsulates the sensitive data in SSL protocol to secure the
communication between SSL client and SSL server via several encryption, authentication, and
secret exchange methods.
1.2 Deployment

1.2.1 Scenario
Below is a figure to show the typical topology for the User Portal application.

The administrator would like to share some of the files in the LAN with his friends and relatives,
including his photos, music, videos, and some of his folders. When the administrator is away
from home, he would also want to remotely access his PC in LAN of NBG-510S via either of the
two protocols, RDP and VNC. If he like, he can even allow some of the clients to remotely access
the desktops of some of his LAN PC’s.
Supposing there’re three clients, John, Lily and guest.
Note: guest is a default client account in the User Portal of NBG-510S. Since anyone who hasn’t
got a user account in the NBG-510S can get into the User Portal using this account, it can’t be
set to use the function of remotely accessing the desktops of the LAN PC’s for security
consideration.
1.2.2 Before configuring on NBG-510S
In most cases in a home network, the WAN IP of the broadband router is got using ADSL
connection. Then an ADSL modem should be placed in front of the NBG-510S. The working
mode of the ADSL modem should be set as Bridge mode.
1.2.3 Configure on NBG-510S
1.2.3.1 Set up the WAN connection.
Go to NetworkWANInternet Connection. The Encapsulation method should be PPPoE. The
Username and Password are what you get from your ISP when you registered the ADSL service.

NBG-510S Support Note

Note: Since the WAN IP address is assigned dynamically from ISP, it can change sometimes. To
ensure remote User Portal clients can access NBG-510S all the time, we can resort to the DDNS
function.
1.2.3.2 Configure the DDNS.
1. Go to NetworkDDNS, click the button to add a DDNS rule.
2. The service provider now NBG-510S supports at the time of writing is
members.dyndns.org. The Domain Names are what you registered on the service
provider, and the User Name and Password are the account you registered on the
service provider.

NBG-510S Support Note

After setting up the DDNS, every time WAN port changes its IP address, the device will update to
the service provider with the new IP address. Remote User Portal clients are then able to access
NBG-510S by the domain name all the time.
1.2.3.3 Configure File Share server
1. Make sure the folders which contain the files that are to be shared are shared in the
LAN network.
Right click the folder, select Properties to let out the folder’s properties window. In the
Sharing tab, check the Share this folder on the network option.
