i installed plugin for Dynamic dns and tried to set it up using dynu.com ... the router i am setting things on is behind NAT, ie its wan has local ip. All the pc's even openwrt router while communicating with internet have public ip which is set based on the router that is connected to internet and is "parent" to the openwrt router.
I wanted to send updates to dynu once my public IP got changed.
