Where is the address translator in this scenario?

The way I've always done it when using a BSD box as the address translator
is to run ntp on the translator.

If your not using a BSD box as the translator but instead some pe-o-yit
little DSL router, bear in mind some of those cannot translate the ntp
protocol.
