DESCRIPTION
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 P-794H 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 P-794H 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 P-794H. You can also set the time manually.
These dates and times are then used in logs.
Use packet tracing and logs for troubleshooting. You can send
logs from the P-794H to an external syslog server.
PPPoE mimics a dial-up Internet access connection.
A UPnP-enabled device can dynamically join a network, obtain
an IP address and convey its capabilities to other devices on
the network.
You can configure firewall on the P-794H 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.
You can efficiently manage traffic on your network by reserving
bandwidth 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 P-794H.
