Network Features
NAT allows multiple PCs to connect to an Internet Service Provider (ISP) using a single Internet access account Point-to-Point Protocol over Ethernet (PPPoE) Client Support If you are a DSL user, the router has a built-in PPPoE client for establishing a DSL link connection with the ISP. There is no need to install a further PPPoE driver on your computersSmart QoS The smart QoS provides stable voice quality while user access internet from private LAN to internet at the same time. This device would start suppressing throughput automatically when VoIP call proceed and keep full speed access when there is no VoIP trafficDDNS (Dynamic Domain Name Server) DDNS is a service that maps Internet domain names to IP addresses. It allows you to provide Internet users with a domain name (instead of an IP Address) to access your Virtual Servers Virtual Server Remote Users can access services such as the Web or FTP at your local site via public IP addresses that can be automatically redirected to local servers configured with private IP addresses VoIP Features
