Prestige 660H Series User's Guide
High Speed Internet Access
Your Prestige ADSL/ADSL2/ADSL2+ router can support downstream transmission rates of up to
24Mbps and upstream transmission rates of 3.5Mbps. Actual speeds attained depend on ISP DSLAM
environment.
Firewall
The Prestige is a stateful inspection firewall with DoS (Denial of Service) protection. By default, when
the firewall is activated, all incoming traffic from the WAN to the LAN is blocked unless it is initiated
from the LAN. The Prestige firewall supports TCP/UDP inspection, DoS detection and prevention,
real time alerts, reports and logs.
You can configure most features of the Prestige via SMT but we
recommend you configure the firewall and content filters using the
web configurator.
Content Filtering
Content filtering allows you to block access to forbidden Internet web sites, schedule when the
Prestige should perform the filtering and give trusted LAN IP addresses unfiltered Internet access.
Traffic Redirect
Traffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect to the
Internet, thus acting as an auxiliary if your regular WAN connection fails.
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the Prestige and other UPnP enabled devices can dynamically
join a network, obtain an IP address and convey its capabilities to other devices on the network.
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 Prestige 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.
Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address used within
one network (for example a private IP address used in a local network) to a different IP address known
within another network (for example a public IP address used on the Internet).
10/100M Auto-negotiating Ethernet/Fast Ethernet Interface(s)
This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and
adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100
Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
Auto-Crossover (MDI/MDI-X) 10/100 Mbps Ethernet Interface(s)
These interfaces automatically adjust to either a crossover or straight-through Ethernet cable.
