I am replacing a Watchguard by a new ASA5540. Part of the configurations of the Watchguard includes NAT based on the origin, I explain: For 2 or but servers in inside, this display to Outside with NAT with single IP and port. The peculiar thing is that, the Watchguard, differentiates on the basis of origin IP (client Outside), redirecting traffic to different servers (inside). somebody knows since to do this with a ASA? or with another additional equipment?
