I am using Transmission BitTorrent client and Retroshare from behind a NAT firewall with port-forwarding/UPnP disabled. However, I still seem to be able to accept incoming connections with these programs, and I am curious how this is possible. In the case of Transmission, I can see the 'I' flag on some peers, which indicates they are an incoming connection. And in the case of Retroshare, I am able to connect with friends that are also behind a NAT firewall. Does anyone know how this is possible from behind a firewall? Is Transmission (and possibly other P2P clients too) doing some kind of NAT traversal? What kind of NAT traversal might they be using?
