P-660HN Series Support Notes locations on the Internet. To use the service, you must first apply an account from several free Web servers such as http://www.dyndns.org/. Without DDNS, we always tell the users to use the WAN IP of the P-660HN-T1A to reach our internal server. It is inconvenient for the users if this IP is dynamic. With DDNS supported by the P-660HN-T1A, 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-660HN-T1A. When the ISP assigns the P-660HN-T1A a new IP, the P-660HN-T1A updates this IP to DDNS server 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. 10. When do I need DDNS service? When you want your internal server to be accessed by using DNS name rather than using the dynamic IP address we can use the DDNS service. The DDNS server allows to alias a dynamic IP address to a static hostname. Whenever the ISP assigns you a new IP, the P-660HN-T1A sends this IP to the DDNS server for its updates. 11. What is DDNS wildcard? Does the P-660HN-T1A support DDNS wildcard? Some DDNS servers support the wildcard feature which allows the hostname, *.yourhost.dyndns.org, to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful when there are multiple servers inside and you want users to be able to use things such as www.yourhost.dyndns.org and still reach your hostname. Yes, the P-660HN-T1A supports DDNS wildcard that http://www.dyndns.org/ supports. When using wildcard, you simply enter yourhost.dyndns.org in the Host field in Menu 1.1 Configure Dynamic DNS. 12. What is Traffic Shaping? Traffic Shaping allocates the bandwidth to WAN dynamically and aims at boosting the efficiency of the bandwidth. If there are serveral VCs in the P-660HN-T1A but only one VC activated at one time, the P-660HN-T1A allocates all the Bandwidth to the VC and the VC gets full bandwidth. If another VCs are activated later, the bandwidth is yield to other VCs after ward. 14 All contents copyright © 2010 ZyXEL Communications Corporation.
