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.

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.
