On top of this it has monitoring logic to warn about udp packets received to unknown port and erroneous udp packets License GPL. A User Datagram Protocol port is an internetworking software abstraction, not a physical thing like a USB port. If you change the default ports after installation, you must manually reconfigure Windows firewall rules to allow access on the updated ports. For instance if you like using hacked clients and decide to turn fly on, you first send packets to the server, the server then handles it from there. LDAP always uses TCP - this is true and why not UDP because a secure connection is established between client and server to send the data and this can be done only using TCP not UDP.
