NAT-aware multipath tracerouting tool
Dublin Traceroute uses the techniques invented by the authors of Paris-traceroute to enumerate the paths of ECMP flow-based load balancing, but also introduces a new technique for NAT detection. It forges the IP ID in the probe packet and analyzes the responses in order to detect all the encountered NATs.
