Hi i have setup a lan connection and setup 10+ cluster nodes and 1 master node i am able to curl nginx server internally but not from external in the lan.

How do you try to contact your workers ? via NodePort ?
To contact via NodePort, your servers need to be in the same LAN of you, or directly exposed to internet.
If your on a LAN, you will need to use port-redirection on your ADSL/Router.
