Without DDNS, we always tell the users to use the WAN IP of the P-660 to access the
internal server. It is inconvenient for the users if this IP is dynamic. With DDNS
supported by the P-660, you apply a DNS name (e.g
server (e.g., Web server) from a DDNS server. The outside users can always access
the web server using the www.zyxel.com.tw regardless of the WAN IP of the P-660
When the ISP assigns the P-660 a new IP, the P-660 must inform the DDNS server
the chang e of this IP so that the server can update its IP-to-DNS entry. Once the
IP-to-DNS table in the DDNS server is updated, the DNS name for your web server
(i.e., w ww.zyxel.com.tw) is still usable.
The DDNS server stores password-protected email addresses with IPs and hostnames
and accep ts queries based on email addresses. So, there must be an email entry in the
P-660 menu 1.
The DDNS servers the P-660 supports currently is WWW.DYNDNS.ORG where you
apply the DNS from and update the WAN IP to.

up the DDNS
1. Before configuring the DDNS settings in the P-660, you must register an
a ccount from the DDNS server such as WWW.DYNDNS.ORG first. After the
registration, you have a hostname for your internal server and a password
using to update the IP to the DDNS server.
2. Toggle 'Configure Dynamic DNS' option to 'Yes' and press ENTER for
