This dictionary has the definitions for prefixes such as il- and post-.

Be sure to include the appropriate hyphens when you search.
This is a really good site to put into your favs for future reference.

I typed il- and it gave me 9 results. How do I know which one to use?
In the site I gave you, if you scan down to prefixes... you will see the following:

il- not
illegitimate, illicit, illegal, illegible

http://dictionary.reference.com/

The prefix, ante-, is in that dictionary. I haven't found "nat," either as a prefix or suffix.
