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.
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.
Use this feature to have the ZyXEL Device assign IP addresses, an IP
default gateway and DNS servers to computers on your network.
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
register for this service with a Dynamic DNS service provider.
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).
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.
Use logs for troubleshooting. You can send logs from the ZyXEL Device to
an external syslog server.
A UPnP-enabled device can dynamically join a network, obtain an IP
address and convey its capabilities to other devices on the network.
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. The
firewall supports TCP/UDP inspection, DoS detection and prevention, real
time alerts, reports and logs.
and giving priority to certain types of traffic and/or to particular
computers.
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.
• Via HTTP/Telnet/SSH/SCP/SFTP
• Configurable port number
• Firmware upgrade via HTTP
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.
Your device supports one Permanent Virtual Circuits (PVCs).
Your device's packet filtering function allows added network security and
management.
