retrieved. This solves the problems if your DNS server uses an IP associated
with dynamic IPs.
Without DDNS, we always tell the users to use the WAN IP of the P-660R-Tx
v3 to access the internal server. It is inconvenient for the users if this IP is
dynamic. With DDNS supported by the P-660R-Tx v3, you apply a DNS name
(e.g., www.zyxel.com.tw) for your 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-660R-Tx v3. When the
ISP assigns the P-660R-Tx v3 a new IP, the P-660R-Tx v3 must inform the
DDNS server the change 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., www.zyxel.com.tw) is still usable.
The DDNS server the P-660R-Tx v3 supports currently is
WWW.DYNDNS.ORG where you apply the DNS from and update the WAN IP
to.
Setup the DDNS
1. Before configuring the DDNS settings in the P-660R-Tx v3, you must
register an account 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.
