Cisco VPN :: ASA 5510 - Configuring Client To Site IP Sec VPN With Hairpin

Need configuring Client to Site IP Sec VPN with Hairpin on Cisco ASA5510 - 8.2(1).
 
The following is the Layout:

There are two Leased Lines for Internet access - 1.1.1.1 & 2.2.2.2, the latter being the Standard Default route, the former one is for backup.
 
I have been able to configure  Client to Site IP Sec VPN
1) With access from Outside to only the Internal Network (172.16.0.0/24) behind the asa
2) With Split tunnel with simultaneous assess to internal LAN and Outside Internet.
 
But I have not been able to make traditional Hairpin model work in this scenario.
 
Following is the Running-Cong with Normal Client to Site IP Sec VPN configured with No internal Access:

LIMITATION: Can't Boot into any other ios image for some unavoidable reason, must use 8.2(1)

running-conf  --- Working  normal Client to Site VPN without internet access/split tunnel:
ASA Version 8.2(1)
!
hostname ciscoasa
[ code ].......

Neither Adding dynamic NAT for 192.168.150.0/24 on outside interface works, nor does the sysopt connection permit-vpn works
 
What needs to be done here, to hairpin all the traffic to internet coming from VPN Clients. That is I need clients connected via VPN tunnel, when connected to internet, should have their IP's Nattered  against the internet2-outside interface address 2.2.2.2, as it happens for the Campus Clients (172.16.0.0/16).
