RE: Port Zero

This is correct.
Netstat is showing you that those listeners are waiting to accept
traffic from (Foreign address) any IP (0.0.0.0) and any port (:0).

Hi, I would think that it is cause it is listening and therefore it wont
know the foreign address source port, thats why it is set to zero, it
will
accept any src port coming into that listening port.
