Chapter 1 Getting to Know Your VSG
31
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 another DHCP server to the DHCP clients.
RADIUS (Remote Authentication Dial-In User Service) Client
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.
Built-in Authentication and Local Subscriber Database
The VSG allows you to maintain a subscriber database on the VSG without setting up an
external RADIUS server. Subscriber accounting and authentication can be done using the
local subscriber database.
Accounting
Accounting can be done using an external RADIUS server or the built-in accounting feature.
Local Content and Advertising Links
The VSG can redirect subscribers to a specified web site and display advertising links. This
can be a source of extra online advertising revenues and increased business exposure.
Access Control (Walled Garden)
With the walled garden feature, subscribers are able to access predetermined web sites without
logging in. The VSG blocks other Internet access until the subscribers log in.
E-mail Forwarding
The VSG is able to forward and retrieve e-mail messages when the subscriber’s default e-mail
server is down or behind a firewall.
DNS Proxy
With DNS proxy, the VSG provides DNS redirection when a subscriber’s configured DNS
server is behind a firewall or located in a private Intranet.
