Access the Modem Web Page(http://192.168.1.1)
After successful Login into the Modem user is displayed the following Information.









Here Note down  the WEP Key either in the Notepad  or a Piece of Paper for configuring  the PC/Laptop’s Wi-Fi adapter settings.
It is up to user whether to use the default security settings or change them.
NAT/Firewall  Configuration Settings


DNA-A212 and DNA-A213  are enabled for NAT & Firewall.
Unless the Connections are explicitly allowed Modems will drop all the connections to the inside hosts/services.
User can enable access to the Services hosted by like http/ftp by configuring either Virtual Servers or DMZ.
The main difference  between Virtual Servers and DMZ is that

With Virtual Servers user can open a specific port for the external users and the traffic designated to this : will be rerouted to the Server on his LAN Side.
In case of DMZ any connection initiated by external host/s to the will be rerouted to the PC on his LAN side.
Virtual  Server Settings                                                                                 DMZ Settings



NAT/Firewall  configuration Settings

User can deny  outgoing connections from Internal Hosts   or allow incoming connections from external  hosts  using the Security – IP  Filters configuration.
