The Proto column can have: TCP - The connection is a TCP connection. PING - The connection is an ICMP ECHO connection. UDP - The connection is a UDP connection. RAWIP - The connection uses an IP protocol other than TCP, UDP, or ICMP. The Source and Destination columns show which IP and port on the source interface the connection is coming from, and which interface and port number the connection is going to. 74
