Just start rtpproxy without options and it will listen on the standard 
socket compiled into rtpproxy and nathelper.so.

Yes, when you call the appropriate functions. Read the Getting Started 
document (chapter 1 + the rtpproxy example chapter) to get detailed info.

If you have a firewall that denies all outgoing ports except those 
explicitly opened (most home routers/FW allow outgoing):
SIP messages: udp (and TCP if you use that) port 5060
RTP: udp 35000-65000 (can be changed in rtpproxy's rttp_defines.h)
Both to your SER+RTPPROXY server.
