I have re-configured the VPN with different ID and now VPN is working fine..
I will explain this to All....
There was a configuration in the firewall, used for another VPN...(crytomap id is 20)
crypto map outside_map 20 ipsec-isakmp
crypto map outside_map 20 set peer 18.104.22.168
crypto map outside_map 20 set transform-set ESP-3DES-MD5
Our fault VPN config is as below....
crypto map igsl 20 ipsec-isakmp
crypto map igsl 20 match address 12
crypto map igsl 20 set peer 22.214.171.124
crypto map igsl 20 set transform-set my_company
So, what i did is, i changed the config as below...
crypto map igsl 14 ipsec-isakmp
crypto map igsl 14 match address 12
crypto map igsl 14 set peer 126.96.36.199
crypto map igsl 14 set transform-set iGATE-OC
We are not supposed to use nat zero here, as the client does not want this side network to expose to other side network.. Only this side can access the remote side network..vice versa should not happen..
Now everything is working fine...
The issue has been resolved by myself
Thanks to all who have participated in this session....
