This is our test setup. Any source will hit the ASA5505 Wan interface to a public IP lets say 126.96.36.199. We need to NAT this IP 188.8.131.52 to a local IP of the other side of the LAN (behind Linux firewall) lets say 172.17.100.2 (184.108.40.206 <==>172.17.100.2). How can we do that? Interesting traffic of the IPSec is trafficc generated between 192.168.0.0/16 and 172.17.100.0/24.
So simply what we need to do is when a user hits to the 220.127.116.11 the destination IP of the request should be changed to 172.17.100.2 and the source IP of the request shuold be changed to 192.168.0.0/16 range IP and request shuold be forwarded out of the WAN interface so that traffic will be intersting traffic of the IPSec and will go to the required destination via IPSec tunnel.
We need to know whether this is possible and any help from any one of you will be highly appreciated.
Thanks in advance.
