IP Multicast IP multicast is used to send traffic to a specific group of
computers. The ZyXEL Device supports versions 2 and 3 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. You can send logs from the ZyXEL
Device to an external syslog server.
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.
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 (HTTPS 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
Packet Filters Your device’s packet filtering function allows added network
security and management.
