In my Gateway I can see two available NICs. Is it possible to find both of those values as tags from in the Designer? I know I can see the Gateway address that the client sees in the folder System/Client/Network.

No, but you can use java's builtin networking functions from a gateway script to obtain this information, and more.
Thank you.
