We are students of a University in Uruguay (South America). We are testing a program that integrates Nice to Goalbit. We have configured a Linux Ubuntu box to act as a router between the debian host where Goalbit/Nice is running and the ADSL connection. We used iptables according to the asterisk wiki to simulate the different kind of NATs (full cone, port restricted, restricted cone and symmetric). With the tool pjsua we have detected the nat-types full cone, port restricted and symmetric but when we configure the Ubuntu box to simulate nat type restricted cone the pjsua detects full cone. We wanted another tool to contrast this result but we started the nattest in many situations (mainly debian or ubuntu with firefox or epiphany and it starts but never reachs any result. How long is it supposed to take? Does it require any operating system or browser to run correctly? Does anyone know another tool to do nat type detection or another way to simulate restricted cone nat type? http://goalbit.sourceforge.net/ http://nice.freedesktop.org/wiki/ https://wiki.asterisk.org/wiki/display/TOP/NAT+Traversal+Testing http://www.pjsip.org/pjsua.htm http://nattest.net.in.tum.de/test.php
