I want to configure a NAT Statement on a FWSM so that traffic initiated by an end user to a server with an IP Address of 10.20.x.x network will access it via a corresponding 10.60.x.x address. But, I want all communications initiated by the server to stay at its original IP Address.
Therefore I have a End User trying to access a server. User will type in 10.60.x.x, this hits the FWSM and changes the 10.60.x.x to 10.20.x.x
The return traffic will go back to the user as 10.60.x.x.
But, that server trying to access the internet, will source as 10.20.x.x and will continue its journey as 10.20.x.x
