Interface Grouping and Marking As depicted in the on the Right side
Ethernet Port3 on the Modem is Mapped for IPTV Service.
i.e., Using Ethernet Cable connect IPSTB to the Ethernet Port3.
Ethernet Port4 on the Modem is Mapped for VoIP Service.
i.e., Using Ethernet Cable connect IP Phone to Ethernet Port4.
Following Screenshot shows the Mappings for the IPTV Services.
Wi-Fi configuration Settings
DNA-A213 and DNA-A212 are enabled with Wi-Fi Security.
End User cannot directly Wi-Fi Connect his PC or LAPTOP to the Modem without knowing the Modem Wi-Fi Security Key (WEP Key).
For Wi-Fi access configuration on the PC / Laptop End user must first connect his PC to the Modem Using Ethernet Cable.
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 <Public IP>:<port> will be rerouted to the Server on his LAN Side.
In case of DMZ any connection initiated by external host/s to the <Public IP>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.
Outgoing (Deny) Incoming (Allow)
Also Certain Application can be blocked for Internal Users using Application Filters option.
MAC Address Filters is one option to prevent access to Banned Users with in an small Office.
