Hi,
E.g. if I want to monitor connections to an FTP-server, I would register
a helper
with destination-port set to 21, but this ain't the way it works,
because I saw that
the ftp/irc contrack helpers register a helper with a source port set,
why ?
Tnx,
greetz

I assume because the conntrack works in both directions, you can run both a
server and a client behind it.
