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
AMG1202-T10B/AMG1302-T10B to reach our internal server. It is
inconvenient for the users if this IP is dynamic. With DDNS supported by the
AMG1202-T10B/AMG1302-T10B, 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
AMG1202-T10B/AMG1302-T10B.
When the ISP assigns the AMG1202-T10B/AMG1302-T10B a new IP, the
AMG1202-T10B/AMG1302-T10B 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 AMG1202-T10B/AMG1302-T10B sends this
IP to the DDNS server for its updates.
11. What is DDNS wildcard? Does the
AMG1202-T10B/AMG1302-T10B 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 AMG1202-T10B/AMG1302-T10B 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 several VCs in the
AMG1202-T10B/AMG1302-T10B but only one VC activated at one time, the
AMG1202-T10B/AMG1302-T10B allocates all the Bandwidth to the VC and
