Actually, this rule would only send packets where *both* target and
destination port are 80. What you're looking for is probably a rule where
you're only matching the destination port as 80, or the source port. A
regular http request doesn't have source port 80, it's more likely to be
*from* a random high port (>1024) *to* port 80. And then the response will
be *from* port 80 to the same random high port.
