and I visited the cc.rtmfp.net and got all greens except the first one : knows public ip address of self

Answer 1

you say that cc.rtmfp.net shows all green except for "knows IP address of self".  is that the case on both computers that you're trying to do P2P between?  are your two computers actually on the same LAN?  if one is on a wired network and the other is on WiFi, they may not be on the same LAN and may be double-NATted.  if your network topology involves double-NAT and the two computers aren't on the same LAN, AND the outer-most NAT doesn't do hairpinning, P2P communication might not be possible in that configuration.
if you use the sample 1:1 P2P app, VideoPhoneLabs (link below), can you do P2P between the two computers?  how about on the same computer in two browser windows?

if P2P on one computer works but not between two computers, there is probably a NAT or firewall issue going on.  depending on the results from cc.rtmfp.net on both computers, i might be able to deduce what's going on.
