Broadband Sharing and IP sharing 
The ADSL VOIP Firewall Router supports 4 x 10/100 Mbps auto-negotiating Fast Ethernet 
ports for connection to your PC or LAN and downstream (with built-in ADSL2+ modem) rate 
up to 24Mbps. Power by NAT technology, dozens of network users can surf on the Internet 
and share the ADSL connection simultaneously by using one ISP account and one single IP 
address.

With integrated IEEE802.11g Wireless Access Point (up to 54Mbps), the device offers quick 
and easy access among wired network and  wireless network. The Wireless  Router also 
supports WPA/WPA2 security, it increases the level of data protection and access control for 
Wireless LAN. Reverse-SMA 5 dBi Antenna provides extended coverage.

The device is provided with a FXS port which allows using the normal PSTN phone like an 
actual VoIP phone.  
The VoIP feature of the Router allows to make voice phone calls via Internet with an 
important reduction of the costs.  
Moreover, with the subscription of a contract with a VoIP service provider, it will be possible 
to make conversations with normal phones with very low fares. The router integrates RJ11 
FXO port for inbound and outbound calls transmitted through PSTN. Users can receive 
phone calls from PSTN while enjoying VoIP call service at the same time. In addition, the 
device automatically fallbacks to lifeline POTS to enable making normal phone calls when 
there is power outage, or when the Internet connection is down.

by outside users. Not only provide the natural firewall function (Network Address Translation,
