There is no necessary link between ULA addresses and NAT. You don't
have to NAT ULA, *ever*. If you need public addresses, go get them.
There are enough.

IMHO one should use ULA in only three situations:

- a completely isolated network
- for internal communications e.g. fabric management)
- for testing
