I think, though I am willing to be wrong on this, to match the first line
the source port must equal telnet, while the destination port is not
specified. To match the second line, the source and destination ports must
equal telnet. Does that result in a functional difference? Not to my
knowledge, at least not in the case of a vanilla telnet application, where
the source and destination ports are likely to be the same number.
Suppose instead of "telnet" the number "1099" were used (or any arbitraty
port)... Would that make a difference between the two lines - yes, I think
so...
