Multiple External IP Addresses

Unanswered Question

I'm new to the world of cisco. (asa 5510).

I have a rack at a data center that has multiple IP addresses - thru (obviously not the acutal addresses.)

I need to integrate it slowly into my rack, pulling one server behind it at a time.

How do i configure a single ethernet port to respond to multiple ip addresses?

For example - today i would like the external interface to answer to and tomorrow i'd like to add in, the the next day, and so on.

You can only assign one IP address per ASA interface. However, you can create static NAT translations to have the firewall ARP for several IPs.

For example you have the interface with IP address, you want to NAT the to an inside server with address You can use the static command as follows:

static (inside,outside) netmask

This will create the static NAT translation and all packets for will be sent to as long as they are permitted on the outside access list. Below you will find the command reference link that has some examples:
