ZyXEL Communications P-660RU-Tx User Manual

P-660RU-Tx User’s Guide

Dynamic DNS allows you to update your current dynamic IP address with one or 
many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-
SeeMe, etc.). You can also access your FTP server or Web site on your own 
computer using a domain name (for instance myhost.dhs.org, where myhost is a 
name of your choice) that will never change instead of using an IP address that 
changes each time you reconnect. Your friends or relatives will always be able to 
call you even if they don't know your IP address.

First of all, you need to have registered a dynamic DNS account with 
www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP 
server that would still like to have a domain name. The Dynamic DNS service 
provider will give you a password or key. 

Use the Dynamic DNS screen (

) to enable DDNS and 

configure the DDNS settings on the P-660RU-Tx.

Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be 
aliased to the same IP address as yourhost.dyndns.org. This feature is useful if 
you want to be able to use, for example, www.yourhost.dyndns.org and still reach 
your hostname.

If you have a private WAN IP address, then you cannot use Dynamic DNS.
