[Asterisk-Users] Traversing the NAT

[Olle E. Johansson]

All of us SIP users have problems with NAT boxes from hell... :-)

There's some components that needs to be documented, like

* What's STUNs role and how do we implement it alongside with NAT
   (maybe Vovida.org stun server)
* What is the function of NAT=yes in sip.conf ;-)
* Do I have any use of SIProxd in handling this?
* Where do I place my asterisk - outside the firewall giving inside clients a problem
   or inside the firewall, making it a problem for Asterisk to connect to outside SIP
   servers, like fwd.pulver.com
* What's the role of "Outbound SIP server"-support in clients?

Any comments, explanations, suggestions, examples would be fine so we can put
together a FAQ on Asterisk, SIP and the NAT problem. Maybe on the SIPwiki?
I haven't got all the knowledge here, but can edit together bits and pieces
from those who understand it or just implemented solutions.
