Question about best practices for multiple Public IPs

[roblaw1980]

So I have a question on what the best way to handle multiple public IP addresses is on an ASA appliance.

Which of these two options is best?

Use a single public interface with the whole range of IPs assigned to it via static ARP table entries

(This is how the device has been configured)

Or assign a single public IP to the physical interface, and create virtual interfaces for each of the other addresses.

Thanks for your input.

Most used solution is to put a single public IP in the range on the outside interface of your ASA. and use the others in NAT rules. to which the ASA will respond on the outside interface
