Any IP
The Any IP feature allows a computer to access the Internet and the ZyXEL Device without
changing the network settings (such as IP address and subnet mask) of the computer, when the
IP addresses of the computer and the ZyXEL Device are not in the same subnet.
Firewall
The ZyXEL Device 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 ZyXEL Device firewall supports TCP/UDP
inspection, DoS detection and prevention, real time alerts, reports and logs.
Content Filtering
Content filtering allows you to block access to forbidden Internet web sites, schedule when the
ZyXEL Device 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 ZyXEL Device cannot
connect to the Internet, thus acting as an auxiliary if your regular WAN connection fails.
Media Bandwidth Management
ZyXEL's Media Bandwidth Management allows you to specify bandwidth classes based on an
application and/or subnet. You can allocate specific amounts of bandwidth capacity
(bandwidth budgets) to different bandwidth classes.
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the ZyXEL Device 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 (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 ZyXEL Device 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. The ZyXEL Device also includes PPPoE idle time-out
(the PPPoE connection terminates after a period of no traffic that you configure) and PPPoE
Dial-on-Demand (the PPPoE connection is brought up only when an Internet access request is
made).
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).
