Configuration Backup &

Restoration

Make a copy of the ZyXEL Device’s configuration. You can put it back on

the ZyXEL Device later if you decide to revert back to an earlier

configuration.

Network Address

Translation (NAT)

Each computer on your network must have its own unique IP address. Use

NAT to convert your public IP address(es) to multiple private IP addresses

for the computers on your network.

Port Forwarding If you have a server (mail or web server for example) on your network, you

can use this feature to let people access it from the Internet.

DHCP (Dynamic Host

Configuration Protocol)

Use this feature to have the ZyXEL Device assign IP addresses, an IP

default gateway and DNS servers to computers on your network. Your

device can also act as a surrogate DHCP server (DHCP Relay) where it

relays IP address assignment from the actual real DHCP server to the

clients.

Dynamic DNS Support With Dynamic DNS (Domain Name System) support, you can use a fixed

URL, www.zyxel.com for example, with a dynamic IP address. You must

IP Multicast IP multicast is used to send traffic to a specific group of computers. The

ZyXEL Device supports versions 1 and 2 of IGMP (Internet Group

Management Protocol) used to join multicast groups (see RFC 2236).

Time and Date Get the current time and date from an external server when you turn on your

ZyXEL Device. You can also set the time manually. These dates and times

are then used in logs.

Logs Use logs for troubleshooting.

Universal Plug and Play

(UPnP)

A UPnP-enabled device can dynamically join a network, obtain an IP

address and convey its capabilities to other devices on the network.

Firewall Your device has 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.

IP/MAC Address Filters Your device’s packet filtering function allows added network security and

management.

Application Filter Application filter allows you to block instant messaging programs.

URL Filter URL filter allows you to block access to Internet web sites that contain key

words (that you specify) in the URL.

QoS (Quality of Service) You can efficiently manage traffic on your network by reserving bandwidth

and giving priority to certain types of traffic and/or to particular computers.

Remote Management This allows you to decide whether a service (HTTP or FTP traffic for

example) from a computer on a network (LAN or WAN for example) can

access the ZyXEL Device.

PPPoE Support

(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

your 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.

Other PPPoE Features PPPoE idle time out

PPPoE dial on demand

Multiple PVC

(Permanent Virtual

Circuits) Support

Your device supports up to 8 Permanent Virtual Circuits (PVCs).
