Hi Experts
The topology is attached
Ping is Successful for the following:
PC1 to all interfaces and to PC2 as well. Ping Fails from PC1 to ASA G0/0
(I am using Ccproxy server to share the Internet on PC2: pc on the right side of the topology), that's why I have to telnet to that PC2 from PC1 to connect to that to Ping outside world (google.com).
I can surf the Internet from PC1 using the proxy server's address of 192.168.137.1(PC2)
Now, I can ping from R2's fa0/1(192.168.137.2) to PC2(192.168.137 and vice versa but I cannot ping to google.com from R2.
What is the reason?
Please help

Hello,
your drawing doesn't match the configurations you have sent, so it is hard to troubleshoot:
R2
interface FastEthernet0/1
ip address 10.1.1.100 255.255.255.0
duplex auto
speed auto
In your drawing that interface has IP address 192.168.137.2/24 ?
R1
interface FastEthernet0/1
no ip address
shutdown
duplex auto
speed auto
In your drawing this interface has IP address 172.16.0.2/16 ?
Also, post the full configuration of the ASA.

Now I have made correction in my post. Now the IP config reflects the Topology.
the sh run of ASA is complete here.

Hi,
I think you have a network loop:
On R2,
ip route 0.0.0.0 0.0.0.0 8.8.8.254
And on ASA,
route outside 0.0.0.0 0.0.0.0 8.8.8.8 1
I guess, you will need to change the default route on R2 as follows:
ip route 0.0.0.0 0.0.0.0 192.168.137.1
HTH,

Ok. Now removed
On R2,
ip route 0.0.0.0 0.0.0.0 8.8.8.254
I have only one default route now on R2:
ip route 0.0.0.0 0.0.0.0 192.168.137.1
