I've always forwarded port 5060 and all the RTP ports, in my case 
16000-16100, directly to my Asterisk box and I've never had problems. 
For SIP you really need to forward the RTP ports you expect to use 
and you might as well forward 5060 as that's the only place you want it to go.

Or, that's my belief. Try it and see, but find out what RTP ports you 
need by looking in rtp.conf for the lines:

rtpstart=16000
rtpend=16100

I picked those numbers because I thought using the default huge range 
made no sense and I've never had a problem with my no more than 3 
calls at a time world.
