You should use an extended ping from the router and use a source interface.

maybe that is the reason i cant ping from router?
Does the line forward all trafic from my Cel 0 directly to my wan interface, While (I am/ the router ) is in the midle ?

Hi,
Can you do following:
-logging console debug
- no service timestamp debug
- access-list 199 permit icmp any any
-debug ip packet detail 199
then ping 8.8.8.8 rep 1
And post output.
Regards.
Alain
