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. 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.
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. The 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 Internet web sites
that contain key words (that you specify) in the URL. You can also
schedule when to perform the filtering and give trusted LAN IP
addresses unfiltered Internet access.
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.
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.
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.
IPSec VPN Capability Establish a Virtual Private Network (VPN) to connect with business
partners and branch offices using data encryption and the Internet
to provide secure communications without the expense of leased
site-to-site lines. The ZyXEL Device VPN is based on the IPSec
standard and is interoperable with other IPSec-based VPN
products.
The ZyXEL Device supports up to two simultaneous IPSec
connections.
Other PPPoE Features PPPoE idle time out
PPPoE dial on demand
