1-4 Getting to Know Your HomeSafe
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).
Traffic Redirect
Traffic Redirect forwards WAN traffic to a backup gateway on the LAN when the HomeSafe
cannot connect to the Internet, thus acting as an auxiliary backup when your regular WAN
connection fails.
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.
DHCP (Dynamic Host Configuration Protocol)
DHCP (Dynamic Host Configuration Protocol) allows the individual client computers to obtain
the TCP/IP configuration at start-up from a centralized DHCP server. The HomeSafe has built-in
DHCP server capability, enabled by default, which means it can assign IP addresses, an IP default
gateway and DNS servers to all systems that support the DHCP client. The HomeSafe can also
act as a surrogate DHCP server where it relays IP address assignments from the actual DHCP
server to the clients.
Any IP
The Any IP feature allows a computer to access the Internet without changing the network
settings (such as IP address and subnet mask) of the computer, when the IP addresses of the
computer and the HomeSafe are not in the same subnet.
Full Network Management
The embedded web configurator is an all-platform web-based utility that allows you to easily
access the HomeSafe’s management settings and configure the firewall. Most functions of the
HomeSafe are also software configurable via the SMT (System Management Terminal) interface.
The SMT is a menu-driven interface that you can access over a telnet connection.
RoadRunner Support
In addition to standard cable modem services, the HomeSafe supports Time Warner’s
RoadRunner Service.

configuration file backups and restoration.
