Can I only NAT internal servers to the subnet of the ASA outside interface?

[gwhuang5398]

ASA's outside interface is a /24 in public address space. I also have a few different /24 public subnets that can be used for NAT. When I static NAT internal servers, do I have to NAT them to the /24 of the outside interface or can I use a difference available /24 subnet? What's the best practice when picking available public subnets for NAT?

Thanks a lot

yes, You can also use a different public ip range from the same ISP, The ASA will proxy arp those ip addresses as well.

Hi,

That doesn't make any difference. You can use IP's from any pool
