DDNS
This chapter describes how to configure dynamic DNS (DDNS) services for the UAG.
19.1 DDNS Overview
DNS maps a domain name to a corresponding IP address and vice versa. Similarly, dynamic DNS
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 IP address.
Note: You must have a public WAN IP address to use Dynamic DNS.
Set up a dynamic DNS account with a supported DNS service provider to be able to use Dynamic
DNS services with the UAG. When registration is complete, the DNS service provider gives you a
password or key. At the time of writing, the UAG supports the following DNS service providers. See
the listed websites for details about the DNS services offered by each.
Note: Record your DDNS account’s user name, password, and domain name to use to
configure the UAG.
After, you configure the UAG, it automatically sends updated IP addresses to the DDNS service
provider, which helps redirect traffic accordingly.
