Hello again, Now I want to use the ftp_conntrack, I created a new table : new_table I just used this command : insmod ip_conntrack_ftp iptables -A INPUT -m helper --helper ftp -j new_table do I have to do something to see FTP related packet entering the new_table filter (like standard FTP tracking on RELATED; NEW or somethnig else uponthe port 21 or 20 ...) ? Does the helper do the job alone ? Because on my test bench .... it does nothing at all (maybe I missed something else) Regards. -- Francois LE BOURDELLES <flebourdelles@xxxxxxx>
