 This WRT-300N router is like home wireless router. It has very limited routing function.  It is made to have two network: One in the Internet interface and one in the LAN/wireless interface. And DHCP server for wired and wireless client on the LAN/WLAN.

 The traffic move from the wired/wireless to outside through Internet interface like normal internet access. 

The way you connect your router, you made it a switch basically but then you used the DHCP server on it. It will not send packets to the outside as it does not have route. When a packet comes from 20.76.4.0, it does not know how to reply.

What you can do is like I did on the file I am attaching. You can disable the DHCP on the router, put the IP address on the LAN interface(not the same as you already have on the Router 1). And assign static IP address for you wireless client on the same network range. The gateway on this case is the Route1 and not the Wireless router.

 With this setup, you can ping from other areas.

Hello
I do not have access to PT however looking at that topology, i would check the wifi/fw rtr, make sure:
1- the internet interface is correct and shares the same subnet as rtr1 serial interface
2-  the fw feature is not by default negating icmp-echo, it could be the wlan2 users can ping externally but externally you cannot ping the wlan2 clients
3- the wlan 2 clients subnet is advertised in the network
