and below is my config, but it still not working for me, any suggestions would be appreciated.

hostname xxxxxxx
domain-name dynu.net

names
ddns update method https://api.dynu.com/nic/update?hostname=xxxx.dynu.net&password=xxxxxx
ddns both
interval maximum 0 0 2 0

!
interface GigabitEthernet0/0
description Outside
nameif NBN
security-level 0
ddns update hostname xxxxx.dynu.net
dhcp client update dns server both
ip address dhcp setroute

Thanks
