Need to add second IP to outside interface of ASA 5520

[pjohnson5480]

Here is my scenario. 

We have a block of addresses assigned to us by our ISP.  We need to assign one of these addresses to a vendor we use for traffic to one of their internal devices.  Lets say the address we gave them out of that block of addresses is 1.2.3.4

How do I add that address to the outside interface so that when traffic s sent to it that the traffic actually gets to the ASA as right now when we send traffic to that address it doean't make it to the ASA.

Sorry if I may be asking a dumb question.  Sometimes I do not see the obvious.

Sincerely

Paul

As long as that block of IPs is being routed to your ASA all you should need to do is create a static NAT entry to translate the public IP to the internal IP of the vendor device.
