DNS service providers and run a client on or behind the gateway router (or IPPBX). It is
required to apply an account and create a hostname in the account before configuration. Click

client then uses

with the latest WAN IP address at
DynDNS
or

seconds
periodically.

. The
refresh interval is usually between 60 ~ 600 seconds depending on the volatility of WAN IP
