Hi.. The messenger is capable travel behind NAT and firewals. In my opinion, that is possible if the port is known as a default port like 80 or 443 or some ftp or some else known port which is opened in the firewalls. But very often the incoming traffic is blocked by firewalls, so the stream like (udp) traffic is blocked away.. that's a problem.. The stream should be packet by STUN or some else.. so it is cabaple to travel throught firewalls, and NAT's

STUN does a lot of things to traverse Firewall, but you can never be too sure with STUN. That's why they invented TURN and then ICE. That's also why there are strategies to use port 80,443, UDP or TCP. Sébastien is right. The only way to solve Steven problem is to better understand the Nat/Firewall environment when he made is test, and see how WengoPhone / Skype tried to find its way out. Steven: 2 ethereal traces of the 2 different tests could be handy in order to try and understand something. Also the logs from WengoPhone. Jerome Ps: for more information on Skype's strategy for example, you have this kind of old document: http://www1.cs.columbia.edu/~library/TR-repository/reports/reports-2004/cucs -039-04.pdf -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] De la part de Tomi Luhtala Envoyé : jeudi 19 octobre 2006 08:51 À : Sebastien Tricaud Cc : [email protected] Objet : Re: [Wengophone-devel] is it improvable: firewall pass through Hi..
