P-660R-Tx Series Support Note s
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 to
access the internal server. It is inconvenient for the users if this IP is dynamic.
With DDNS supported by the P-660R-Tx, 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. When the ISP assigns the
P-660R-Tx a new IP, the P-660R-Tx 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 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, 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.
