I believe I found this in the FAQ: 6.1. How can I easily use Ekiga behind a NAT/PAT gateway? Ekiga has extensive and improved NAT support thanks to STUN. In 99% of the cases, you do not have any configuration to do, and you can even be reachable from the outside without any port forwarding. SIP only: The following explanation is valid only for SIP. Please read below for H.323. The first thing to do is to run the configuration assistant NAT test: If it reports "Cone NAT" or "Port Restricted NAT" you just have to answer "yes" to the dialog asking you to activate STUN support. You do not have to do anything else. You will be reachable from the outside. If it reports "Symmetric NAT" and that you are using GNU/Linux, please use the script (or a variation of it) given below. You can run the NAT test again, you will notice that your NAT will behave as a "Cone NAT" or "Port Restricted NAT" as in case 1). That script is safe, it does not forward any port and the default POLICY is to DROP everything. If it reports "Symmetric NAT" and that you are not using GNU/Linux, then you are not part of the 99% of lucky users. You will have to forward UDP ports 5000 to 5100 to your internal machine. Run the test again, it should report "Cone NAT" or "Port Restricted NAT" and it will work.
Ahhh ... good info. Here is a link for reference and context: http://www.gnomemeeting.org/index.php?rub=3&pos=0&faqpage=x161.html#AEN163 For those who may not know, SIP is for the audio stream and H.323 is for the video stream. /Mike
