2.1.5. Dynamic DNS Setup
A dynamic WAN IP address causes difficulty for inbound connections from remote
clients for IP PBX systems. A popular work-around is to adopt domain names
provided by a DynDNS server and run a DynDNS client on or behind the gateway
router (or IPPBX). It is required to apply an account first and create a hostname in the
account before configuration. Select System
→
Dynamic DNS Setup, check Enable
box, and enter the account infomations and refresh interval to activate a DynDNS
client. The client then uses Username and Password to access its account and
update the Hostname with the latest WAN IP address at the DynDNS server in
Interval seconds periodically.
Enable DynDNS
Select Enable button, enter the Username, Password, Hostname, and Interval, and
then click APPLY button. Typical hostname has a form of <hostname>.dyndns.org.
The refresh interval can be from 60 to 600 seconds depending on the volatility of
WAN IP assignment. For example, you can visit
http://www.no-ip.com
to apply an
account with your own username and password and acquire a hostname, like
VOI-9200.no-ip.org, named by yourself.
Disable DynDNS
Select Disable button, and then click APPLY button.
