Hello,

Add the following

fixup protocol ICMP

If this does not make the difference do the following:

1) Check the Ip address on your PC, make sure the ASA is the default gateway?

2) Ping the ISP address ( The default gateway of the ASA)

3) Share the complete output of show run nat

Let me know the result
