 If tcpprep is unable to determine one or more networks which only contains
 servers and unknowns, tcpprep will abort.
 
+Port mode looks at the source/destination port of the TCP or UDP packet.
+Client traffic goes out the primary interface, and server traffic out the
+secondary interface.  Non-TCP and UDP traffic goes out the same interface
+as non-IP traffic does.  Note that this mode does not track IP addresses;
+so an IP may appear to jump between interfaces depending on if it is the
+client or server.
+
 In all cases, servers are sent out the primary interface, and clients out the 
 secondary.
