Chapter 1 Getting to Know Your VSG

PPPoE Support (RFC2516)

PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your

ISP to use their existing network configuration with newer broadband technologies such as

ADSL. The PPPoE driver on the VSG is transparent to the computers on the LAN, which see

only Ethernet and are not aware of PPPoE; thus saving you from having to manage PPPoE

clients on individual computers.

PPTP Support

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of

data from a remote client to a private server, creating a Virtual Private Network (VPN) using a

TCP/IP-based network. PPTP supports on-demand, multi-protocol and virtual private

networking over public networks, such as the Internet. Subscribers can use PPTP to connect to

a broadband modem to achieve access to high-speed data networks via a familiar "dialup

networking" user interface.

Reset Button

Use the reset button to restore the VSG back to its factory defaults.

Plug-and-Play Internet Access

The VSG provides Internet access to attached computer(s) without extra software installation

or computer configuration. In addition, with transparent proxy, the VSG resolves any

incompatible proxy settings.

Port Forwarding

Use this feature to forward incoming service requests to a server on your local network.

DHCP Support

DHCP (Dynamic Host Configuration Protocol) allows the individual computers (DHCP

clients) to obtain TCP/IP configuration at start-up from a centralized DHCP server. The VSG

has built-in DHCP server capability. It can assign IP addresses, an IP default gateway and

DNS servers to DHCP clients. The VSG can also act as a surrogate DHCP server (DHCP

Relay) where it relays IP address assignment from the actual real DHCP server to the DHCP

clients.

RADIUS (Remote Authentication Dial-In User Service)

The VSG allows you to maintain a central subscriber database on an external RADIUS server.

Subscriber accounting and authentication is then done through the external RADIUS server. In

addition, the VSG supports Vendor Specific Attributes (VSAs) that allows enforcement of

upload/download bandwidth limits or specific advertisement web page per subscriber.
