Force a DDNS Update

To force a DDNS update, SSH into your USG or Edgerouter and type:

update dns dynamic interface {WAN IP}

For Example:

update dns dynamic interface eth0 (USG 3)

or

update dns dynamic interface eth2 (USG Pro)

To show the current status:

show dns dynamic status

which will show

interface    : eth2
ip address   : WAN IP
host-name    : unifi.example.com
