Indeed, the ports are different, that's why adding received is
important in this situation.<br>
<br>
While local ip and local port are in most of the cases also unique
for devices behind a nat router, it is not 100% true, because there
can be many layers of NATs, which can result in seeing same local
ip/port for devices.<br>

information to Path helps to identify properly the
connection to be used. Because both devices are behind the
same NAT, practically they show the same source IP when
they send traffic to server.<br>
