We have an issue with a 515 PIX. Here is the situation:
1) Users use a client/server application that is remotely located. The local network at site 1 where the users are located uses private addressing 192.168.x.x and NAT to the exterior with the 515 to a IP of a private WAN in the 10.x.x.x
2) The remote server is at let's say 10.128.65.40, so the nat is done at the 515 on the source address
3) This application have a backup server located INSIDE site 1. Therefore, the users always uses the foreign 10.128.65.40 address and the network at site 1 have to nat this adresse to an INSIDE address in the 192.168.x.x. to the backup server.
How do you do that? Nating the destination address to redirect the traffic to internal?
