Current Adtran ASE switches (1570,1560,1760 models) do not support NAT. NAT is a feature built into our routing/firewall software on AOS router products such as the 3140, 3148 and 4148 (as well as legacy platforms).
The feature matrices for the different product lines can be found at the below link and provides a detailed look at the features available on the different platforms.
