Use the web configurator to easily configure the rich range of
features on the P-660RU-Tx.
Download new firmware (when available) from the ZyXEL web site
and use the web configurator, an FTP or a TFTP tool to put it on
the P-660RU-Tx.
Note: Only upload firmware for your specific model!
Make a copy of the P-660RU-Tx's configuration. You can put it
back on the P-660RU-Tx later if you decide to revert back to an
earlier configuration.
Each computer on your network must have its own unique IP
address. Use NAT to convert your public IP address(es) to multiple
private IP addresses for the computers on your network.
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-660RU-Tx 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.
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-660RU-Tx 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-660RU-Tx. You can also set the time manually.
These dates and times are then used in logs.
Use logs for troubleshooting.
A UPnP-enabled device can dynamically join a network, obtain an
IP address and convey its capabilities to other devices on the
network.
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.
Your device's packet filtering function allows added network
security and management.
Application filter allows you to block instant messaging programs.
URL filter allows you to block access to Internet web sites that
contain key words (that you specify) in the URL.
You can efficiently manage traffic on your network by reserving
bandwidth and giving priority to certain types of traffic and/or to
particular computers.
