FTP is an archaic protocol and one of my great hates.
:-) It baffles many people. I set it up once, then a few months later I have to read it up again.
Zeigler's book "Linux Firewalls" may be old, my copy has a copyright date of 2000, and is based on ipchains rather than iptables, but it is still authoritative about the principles. The second and later editions & revisions deal with iptables. Q.V. http://www.amazon.com/exec/obidos/ASIN/0735710996/
It is automated on SuSEfirewal2, no need to set up iptables yourself :-) The problem is the router... it depends on what it has. Some routers do offer ftp on an external usb disk, I think mine does. Dunno. Or, set the router to redirect everything, unfiltered, unmanaged, to another machine inside. This other machine would do firewall, ftp and NAT for the rest. -- Cheers / Saludos, Carlos E. R.
