Ok Guys Above is the Config
here is the test iam doing
pinging from the internal interface of asa to internal hosts (same interface) Successfull
Pinging from the asa external interface to the external router and beyond to the internet is ok
Pinging from the asa exernal interface to internal hosts unsuccessfull (no route to host)
Pinging from the asa internal interface to internet unsuccessfull (no route to host)
i have turned on the option to allow ping to and from interfaces as i know this is off by default.
