asterisk users - Apr 2005 - need to ask you about your dlink and NAT/voip

To whom it may concern, 

I was searching across the digium list for another issues and noticed you made 
sip work across nat on a dlink routers? I have had nothing with three 
different people making a sucsessfully connection from my xlite to asterisk 
box to a D-link DI-704p router. Dispite opening up ports virtual server ports 
5060  and 10000-10010 for rtp it only passes my voice to the end user. I do 
not hear him calling me. Dont know what else could be causing the issue 
unless its a dlink/nat issue. I reside on #asterisk on freenode alot.
