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. These dates and times are
then used in logs.
Syslog The ZyXEL Device can send syslogs to an external syslog
server.
PPPoE PPPoE mimics a dial-up Internet access connection.
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 You can configure firewall on the ZyXEL Device for secure
Internet access. When the firewall is on, by default, all
incoming traffic from the Internet to your network is blocked
unless it is initiated from your network. This means that probes
from the outside to your network are not allowed, but you can
safely browse the Internet and download files for example.
Access Control This allows you to decide whether a service (HTTP traffic for
example) from a computer on the LAN can access the ZyXEL
Device.
