Hi,
in nf_conntrack_ftp.c for example we find
ftp[i][j].tuple.src.u.tcp.port = htons(ports[i]);
assuming the user does not specify any ports on modprobe, the default
port list defaults to {21}, so ftp[0][x].tuple.src will contain port 21.
But even ftp connections to non-21 ports are inspected for PORT
commands. So, where is the magic that actually ignores the port and
makes it work, given that __nf_ct_helper_find/helper_hash hashes on the
port?
