WAN IP range

Hi,

In my network, I have a /24 block of valid IP. on my former UTM (sophos UTM 9) I used to segment this block as several smaller blocks on different virtual interfaces which wastes a lot of IP's.

now on new XG, I intend to assign all valid IP's to the WAN interface and setup one to one nat to internal servers.

it seems I have to add each single IP one by one as an alias to wan IP, is it correct?

also is this solution a suggested practice to handle my block of valid IP's?

Thanks
