          Hello Mohamed,


          Below you will find a few things to consider, if you have not done so already:


          The firewall automatically drops traffic going between interfaces with different security levels. You need to permit the type of traffic you want to flow from your Inside interface to your Outside.


          You will need to configure static routing to route traffic destined to the Internet, and destined for your internal network. 


          If your router has multiple interfaces, check the routing to make sure the traffic is flowing to and from the ASA correctly.
