Dear Nasheer,
Please check the following and answer to better understand your issue:
- do u have a configured ip on the router which is part of the subnets which are on you LAN side of the router? this is required to ping from the router to the LAN IP subnets
- do you have a configured ip on each of the wan interface. try pinging to those ip address.
- how does the routing looks like?
- are the wan interface facing to the internet?
- can you share a diagram of the setup?
Answers to these questions will help me understand.

Syed
