configuring WRT300n wireless router, troubleshooting default gateway

[Mattjafari]

hi there, there is an issue with my wireless router. the ping command reaches the wireless router but does not go through the wireless router. so, the connectivity between the wireless router and the default gateway router has an issue which I cannot solve. I would appreciate it if u check the image below and guide me somehow

 The WRT300N is meant for traffic from inside to outside. If you need to send traffic from outside to inside you need to use port-forwading but ICMP is not comtemplated. Only TCP and UDP based protocol. 

  What you can do is trick the router and connect it using the lan interface and not the internet interface. But, this way it would be an access point and not a wireless router. 

In Application & Gaming, you have the option to accept traffic from outside to inside but not ICMP.

not working again, even it does not load the website in web browser. if the wrt300n do not work at any cases, how should I change the topology and place something else for this office to work both with lan and wlan?

Zip your packettracer file and add here. Explain what is not working, let me see. 

[Mattjafari]

there are one main office, and two branches. the main office works fine, but the branches does not have access to the internet(cloud). here is the complete file you can check it. 
thank you

You are missing routes

[Mattjafari]

thank you so much, can you tell me exactly what did I miss and how you found out?

[Flavio Miranda]

@Mattjafari  sure

I enabled ospf on Routerstanbul and Routerizmir. 

I found out by running trace route and I saw that the packet stopped on these routers.
