Profile Select this check box to use this DDNS entry.
Profile Name When you are adding a DDNS entry, type a descriptive name for this DDNS entry in
the ZyWALL. You may use 1-31 alphanumeric characters, underscores(
_ ), or
dashes (-), but the first character cannot be a number. This value is case-sensitive.
This field is read-only when you are editing an entry.
DDNS Type Select the type of DDNS service you are using.
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 Click Advanced to display more settings. Click Basic to display fewer 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 - 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.
Custom IP This field is only available when the IP Address is Custom. Type the IP address to
use for the domain name.
Backup Binding
Address 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.
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. Select None
to not use a backup address.
