Can I use ACLs to control when a router performs a static NAT?
I have a situation where I need to NAT an address if it came from IP address A, but not if it came from IP address B. The problem is that both A & B come into my router on the same interface ... which means I have "ip nat outside" defined on the interface.
Device A needs NAT because it dosen't have a route to the real IP address. Device B just sends to the real IP address. The problem occures on the reply, as the router always NAT's the the source address using my static NAT enry.
I would like to control whether or not the router NAT's by use of an ACL, but can't find any way to configure it.
