How can you claim 'silent fw' if it was the source of an ftp

Sure, don't change your firewall, but do realize that your argument is
flawed. There is traffic originatimg from the address, so it must be
alive. Simply sending a RST for attempted connections to the ident
port does not tell anyone anything new.
What does block drop gain you over block reject in this case ?
(not a question to debate on the list, just something to think about)
