I have ASA 5505 configured with version 8.2 but unable to ping from ASA to 8.8.8.8 or any public ip. I have following topolgy.
Following is the logical diagram

Hi Rizwan,
Did you down-grade the ASA from 8.2? As per your other discussion you said you were able to ping the internet from the ASA, but now you are unable? Have you cleared the arp cache on the router?
Could you please post the full running configuration of the router as well.

Hi,
Yep I have downgraded ASA to version 8.2 now everything is working fine after a reload
I am configuring IPSEC tunnel on it. Please let me know if I need reverse-route injection and NAT-traversal in it ?
03-02-2014 06:43 AM
I want to pass all my traffic from tunnel. How is it possible ?
03-02-2014 07:01 AM
Since you have a router in front of the ASA, and I presume it is performing NAT as well, then yes you need to enable NAT-T for the IPsec tunnel.
I want to pass all my traffic from tunnel. How is it possible ?
I am assuming this is a site to site tunnel, and I also assume you mean you want to send all traffic through the IPsec tunnel? This is possible by setting the destination address in the crypto ACL as "any".
access-list crypto_ACL extended permit ip 192.168.3.0 255.255.255.0 any
crypto map VPN_MAP 1 match address crypto_ACL
nat (inside) 0 access-list crypto_ACL

Using above mentioned configuration all inside traffic will pass through tunnel without NAT with outside interface.
Is my internet will work from otherside of the tunnel? Please also check route outside command . Please also review my configuration mentioned below.

To get internet access you would need to configure hairpinning on the remote end.
as for the routing you do not need any additional routes configured other than your default route. Besides only one default route can be active on the ASA at any given time.

Can you please send me hairpinning configuration or any link contains information about it.
03-03-2014 12:28 AM
The commands you would need to add are as follows:
same-security-traffic permit intra-interface
nat (outside) 1
You already have the global command in there so you don't need to add that.

Are these configuration are for my side firewall ?
Is there any configuration reqduired at remote end ?

This would be on your ASA, the ASA where internet will be accessed.
