Wireless
Functionality
(wireless devices
only)
Allow the IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n
wireless clients to connect to the P-2812HNU-51c wirelessly.
Enable wireless security (WEP, WPA(2), WPA(2)-PSK) and/or MAC
filtering to protect your wireless network.
Firmware Upgrade Download new firmware (when available) from the ZyXEL web site
and use the web configurator to put it on the P-2812HNU-51c.
Note: Only upload firmware for your specific model!
Configuration Backup
& Restoration
Make a copy of the P-2812HNU-51c’s configuration. You can put it
back on the P-2812HNU-51c later if you decide to revert back to
an earlier configuration.
Port Forwarding 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.
DHCP (Dynamic Host
Configuration
Protocol)
Use this feature to have the P-2812HNU-51c assign IP addresses,
an IP default gateway and DNS servers to computers on your
network. Your device can also act as a surrogate DHCP server
(DHCP Relay) where it relays IP address assignment from the
actual real DHCP server to the clients.
Dynamic DNS
Support
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 IP multicast is used to send traffic to a specific group of
computers. The P-2812HNU-51c 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 P-2812HNU-51c. 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 P-
2812HNU-51c 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.
