The behavior is normal. It is actually a perfect router. NAT is something bad, as it rewrites the packets. The problem with NAT is that some protocols (like SIP) require you to change the private IP address inside the SIP packet. A good NAT implementation should be able to do it for most common protocols. Most NAT implementations can deal with FTP transparently for you. Unfortunately, until recently, that was not the case with SIP and you needed workarounds like STUN or port forwarding. But recently, more and more routers started to have a NAT implementation that supports SIP. In that case, no port forwarding, no STUN are required. That is the perfect situation. Please note that it only forwards RTP ports because it knows that is a connection you established yourself. It is able to understand what happens. -- _ Damien Sandras (o- //\ Ekiga Softphone : http://www.ekiga.org/ v_/_ Be IP : http://www.beip.be/ FOSDEM : http://www.fosdem.org/ SIP Phone : sip:dsand...@ekiga.net _______________________________________________ ekiga-list mailing list ekiga-list@gnome.org http://mail.gnome.org/mailman/listinfo/ekiga-list
