Chapter 18 DDNS Table 96 Configuration > Network > DDNS > Add (continued) LABEL DESCRIPTION Username Type the user name used when you registered your domain name. You can use up to 31 alphanumeric characters and the underscore. Spaces are not allowed. For a Dynu DDNS entry, this user name is the one you use for logging into the service, not the name recorded in your personal information in the Dynu website. Password Type the password provided by the DDNS provider. You can use up to 64 alphanumeric characters and the underscore. Spaces are not allowed. DDNS Settings Domain name Type the domain name you registered. You can use up to 255 characters. Primary Binding Address Use these fields to set how the ZyWALL determines the IP address that is mapped to your domain name in the DDNS server. The ZyWALL uses the Backup Binding Address if the interface specified by these settings is not available. Interface Select the interface to use for updating the IP address mapped to the domain name. Select Any to let the domain name be used with any interface. IP Address The options available in this field vary by DDNS provider. Interface -The ZyWALL uses the IP address of the specified interface. This option appears when you select a specific interface in the Primary Binding Address Interface field. Auto - If the interface has a dynamic IP address, the DDNS server checks the source IP address of the packets from the ZyWALL for the IP address to use for the domain name. You may want to use this if there are one or more NAT routers between the ZyWALL and the DDNS server. Note: The ZyWALL may not determine the proper IP address if there is an HTTP proxy server between the ZyWALL and the DDNS server. Custom IP Backup Binding Address Interface Custom - If you have a static IP address, you can select this to use it for the domain name. The ZyWALL still sends the static IP address to the DDNS server. This field is only available when the IP Address is Custom. Type the IP address to use for the domain name. Use these fields to set an alternate interface to map the domain name to when the interface specified by the Primary Binding Interface settings is not available. Select the interface to use for updating the IP address mapped to the domain name. Select Any to let the domain name be used with any interface. Select None to not use a backup address.
