Device Management
Use the web configurator to easily configure the rich range of 
features on the P-660RU-Tx.
Firmware Upgrade
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!
Configuration Backup 
& Restoration
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 
earl
i
er configuration.
Network Address 
Translation (NAT)
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.
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-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.
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-660RU-Tx 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-660RU-Tx. You can also set the time manually. 
These dates and times are then used in logs.
Logs
Use logs for troubleshooting.
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.
IP/MAC Address 
Filters
Your device’s packet filtering function allows added network 
security and management.
Application Filter
Application filter allows you to block instant messaging programs.
URL Filter
URL filter allows you to block access to Internet web sites that 
contain key words (that you specify) in the URL.
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.
