[Serusers] Both UA nated in different networks and SER

Hi.
Reading Gettingstarted04.pdf at 1.6.2 from Onsip.org,
seems to me that I _always_ need a rtp relay when
both UA are nated.
Because NAT will not be able to know what ports
must be forwarded to the internal UA.

Is this true?
Is there any scenario where I can have both
UA nated and they can just use SIP signaling
with ser, and stablish the RTP flow between them?

Thanks in advance,
Sebastian.
