Secondary addressing on ASA interface

Does the ASA FWOS support secondary addressing on an interface?

Hi Bridget,

It doesn’t. Is there any reason why you need this?

If it’s for NAT, you can use any IP address that falls in the same subnet of the IP address that you configured on your interfaces…no need to add it as a secondary IP address like we do in Cisco IOS.

If it’s for another subnet, you will have to work with sub-interfaces.
