Prestige 310 Broadband Sharing Gateway

1.2.4 Traffic Redirect

Traffic Redirect forwards WAN traffic to a backup gateway on the LAN when the Prestige cannot connect to
the Internet, thus acting as an auxiliary backup when your regular WAN connection fails.

1.2.5 Port Forwarding

Use this feature to forward incoming service requests to a server on your local network. You may enter a
single port number or a range of port numbers to be forwarded, and the local IP address of the desired server.

1.2.6 Trigger Port Forwarding

LAN computers dynamically take turns using the mapping based on the trigger port. With this feature, you
needn't reconfigure a new IP address each time you want a different computer (as you would with Port
Forwarding).

1.2.7 Internal SPTGEN

Internal SPTGEN (System Parameter Table Generator) lets you configure, save and upload multiple menus at
the same time using just one configuration text file - eliminating the need to navigate and configure
individual SMT menus for each Prestige.

1.2.8 DHCP Support

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (workstations) to obtain the
TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server
capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS
servers to Windows 9X, Windows NT and other systems that support the DHCP client. The Prestige can now
also act as a surrogate DHCP server (DHCP Relay) where it relays IP address assignment from the actual real
DHCP server to the clients.

1.2.9 Dynamic DNS Support

With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the
host to be more easily accessible from various locations on the Internet. You must register for this service
with a Dynamic DNS client.

1.2.10 IP Multicast

Deliver IP packets to a specific group of hosts using IP multicast. IGMP (Internet Group Management
Protocol) is the protocol used to support multicast groups. The latest version is version 2 (see RFC 2236);
the Prestige supports both versions 1 and 2.
