Product Overview Networking The Symantec Firewall/VPN also enables a local area network (LAN). This allows all the connected computers to share files, printers, and other network devices. The multiport 10/100 switch working with the built in DHCP server enables multiple users to connect to a shared network with nothing more than a standard ethernet cable. The DHCP server "leases" IP addresses to computers as they connect to a local network. This combination ensures quick and easy network setup for even the most inexperienced PC users. Also included is PPPoE support and features such as NAT and PAT. Virtual Private Networking (VPN) The VPN feature of the Symantec Firewall/VPN enables secure and inexpensive tunneling between the local site and other sites, such as the central office or ISP. All of the Symantec Firewall/VPN models act as VPN gateways (VPN end points) for gateway to gateway VPN tunnels and remote client VPN to gateway tunnels (model 200R). High Availability / Load Balancing The Symantec Firewall/VPN 200 and 200R models include 2 WAN side ports that can load share across the two ports and even across two service providers using different internet connection technology (for example DSL and cable). Automatic Dial Up Back Up Models 100, 200 and 200R include the ability to interface with an analog modem for auto dial-up backup. The Dial Up Back Up automatically engages a dial-up connection to the internet, using the serial port, if the primary internet connection fails. This ensures some level of connectivity even if your main Internet connection fails. It will automatically disengage when the primary connection returns. The serial port is used for analog or ISDN connections as well as pre-configuring or resetting the unit via a terminal console. The serial port can be used in Back Up mode or as the sole Internet connection of the unit until broadband is available in your area. IP Address Sharing The IP Address Sharing feature allows one or two external IP addresses to be shared across an entire office. This sharing creates many unique internal IP addresses from one or two external IP addresses and enables cost efficient use of Internet connectivity. 1-2

Product Overview
Networking
The Symantec Firewall/VPN also enables a local area network (LAN). This allows all the
connected computers to share files, printers, and other network devices. The multiport 10/100
switch working with the built in DHCP server enables multiple users to connect to a shared
network with nothing more than a standard ethernet cable. The DHCP server "leases" IP addresses
to computers as they connect to a local network. This combination ensures quick and easy network
setup for even the most inexperienced PC users.
Also included is PPPoE support and features such
as NAT and PAT.
Virtual Private Networking (VPN)
The VPN feature of the Symantec Firewall/VPN enables secure and inexpensive tunneling between
the local site and other sites, such as the central office or ISP. All of the Symantec Firewall/VPN
models act as VPN gateways (VPN end points) for gateway to gateway VPN tunnels and remote
client VPN to gateway tunnels (model 200R).
High Availability / Load Balancing
The Symantec Firewall/VPN 200 and 200R models include 2 WAN side ports that can load share
across the two ports and even across two service providers using different internet connection
technology (for example DSL and cable).
Automatic Dial Up Back Up
Models 100, 200 and 200R include the ability to interface with an analog modem for auto dial-up
backup. The Dial Up Back Up automatically engages a dial-up connection to the internet, using the
serial port, if the primary internet connection fails. This ensures some level of connectivity even if
your main Internet connection fails. It will automatically disengage when the primary connection
returns. The serial port is used for analog or ISDN connections as well as pre-configuring or
resetting the unit via a terminal console. The serial port can be used in Back Up mode or as the sole
Internet connection of the unit until broadband is available in your area.
IP Address Sharing
The IP Address Sharing feature allows one or two external IP addresses to be shared across an
entire office. This sharing creates many unique internal IP addresses from one or two external IP
addresses and enables cost efficient use of
Internet connectivity.
