Hi,
Does anyone know what is the purpose of tcp port number 0 ?
I have an experience catching traffic coming from HTTP server with tcp =
port number 0 and destinated to any IP address with tcp port number 0. =
After I put an incoming acces-list that blocked port number 0, a few =
minute later I saw this packet was never being generated again. The =
access-list is applied for incoming traffic.
For example :
access-list 101 deny tcp host HTTPserver eq 0 any log
access-list 101 deny tcp any any eq 0 log
access-list 101 deny tcp any eq 0 any log
access-list 101 permit ip any any
Thank you
