Configuring DDNS
Dynamic DNS (DDNS) is a service that allows computers to use the
same domain name, even when the IP address changes from time
to time (during reboot or when the ISP's DHCP server resets IP
leases). iPBX30 connects to a DDNS service provider whenever the
WAN IP address changes. It supports setting up the web services
such as Web server, FTP server using a domain name instead of
the IP address. DDNS supports the DDNS clients with the following
features:
• Update DNS records (addition) when an external interface
comes up
• Force DNS update
