Chapter 13 DDNS Table 95 Configuration > Network > DDNS > Add (continued) LABEL IP Address DESCRIPTION The options available in this field vary by DDNS provider. Interface -The UAG uses the IP address of the specified interface. This option appears when you select a specific interface in the Backup Binding Address Interface field. Auto -The DDNS server checks the source IP address of the packets from the UAG 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 UAG and the DDNS server. Note: The UAG may not determine the proper IP address if there is an HTTP proxy server between the UAG and the DDNS server. Custom IP Enable Wildcard Custom - If you have a static IP address, you can select this to use it for the domain name. The UAG 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. This option is only available with a DynDNS account. Mail Exchanger Enable the wildcard feature to alias subdomains to be aliased to the same IP address as your (dynamic) domain name. This feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still reach your hostname. This option is only available with a DynDNS account. DynDNS can route e-mail for your domain name to a mail server (called a mail exchanger). For example, DynDNS routes e-mail for [email protected] to the host record specified as the mail exchanger. If you are using this service, type the host record of your mail server here. Otherwise leave the field blank.
