Following instructions on http://www.shorewall.net/FTP.html I started using "modules" file to serve several internal FTP sites on different ports. After last change, I started getting "Invalid argument" when I restarted Shorewall on modules ip_nat_ftp and ip_conntrack_ftp. In the "hard way", I discovered a limitation in the those modules, not in Shorewall. You can only use up to 8 (eight) ports in "ports=" argument. Be aware of. -Guilsson ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc. Get Certified Today Register for a JBoss Training Course.
