35 Chapter 1 Introducing the Prestige

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.

Content Filtering

The Prestige can also block access to web sites containing keywords that you specify. You can

define time periods and days during which content filtering is enabled and include or exclude a

range of users on the LAN from content filtering.

Custom Ring Tones

You can Interactive Voice Response (IVR) on a telephone to record custom ring tones on the

Prestige, and then you can tell the Prestige which tone to use when you get incoming calls and

which tone to use when you put someone on hold.

Bandwidth Management

Bandwidth management allows you to allocate network resources according to defined

policies. This policy-based bandwidth allocation helps your network to better handle real-time

applications such as Voice-over-IP (VoIP).

SIP ALG

The Prestige is a SIP Application Layer Gateway (ALG). It allows VoIP calls to pass through

NAT for devices behind the Prestige (such as a SIP-based VoIP software application on a

computer).

Any IP

The Any IP feature allows a computer to access the Internet and the Prestige without changing

the network settings (such as IP address and subnet mask) of the computer, when the IP

addresses of the computer and the Prestige are not in the same subnet.

10/100Mbps Auto-negotiating Fast Ethernet Interfaces

The 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 10/100 Mbps Ethernet Interfaces

The Ethernet interfaces automatically adjust to either a crossover or straight-through Ethernet

cable.
