CHAPTER 11 DDNS 11.1 DDNS Overview Dynamic DNS (DDNS) services let you use a domain name with a dynamic IP address. 11.1.1 What You Can Do in this Chapter • Use the DDNS screen (see Section 11.2 on page 363) to view a list of the configured DDNS domain names and their details. • Use the DDNS Add/Edit screen (see Section 11.2.1 on page 364) to add a domain name to the Zyxel Device or to edit the configuration of an existing domain name. 11.1.2 What You Need to Know DNS maps a domain name to a corresponding IP address and vice versa. Similarly, Dynamic DNS (DDNS) maps a domain name to a dynamic IP address. As a result, anyone can use the domain name to contact you (in NetMeeting, CU-SeeMe, etc.) or to access your FTP server or Web site, regardless of the current (dynamic) IP address. Note: You must have a public WAN IP address to use Dynamic DNS. You must set up a dynamic DNS account with a supported DNS service provider before you can use Dynamic DNS services with the Zyxel Device. When registration is complete, the DNS service provider gives you a password or key. At the time of writing, the Zyxel Device supports the following DNS service providers. See the listed websites for details about the DNS services offered by each. Table 142 DDNS Service Providers PROVIDER SERVICE TYPES SUPPORTED DynDNS Dynamic DNS, Static DNS, and Custom DNS Dynu Basic, Premium No-IP No-IP Peanut Hull Peanut Hull 3322 3322 Dynamic DNS, 3322 Static DNS Selfhost Selfhost WEBSITE www.dyndns.com www.dynu.com www.no-ip.com www.oray.cn www.3322.org selfhost.de Note: Record your DDNS account's user name, password, and domain name to use to configure the Zyxel Device. After you configure the Zyxel Device, it automatically sends updated IP addresses to the DDNS service provider, which helps redirect traffic accordingly. ZyWALL ATP Series User's Guide 362
