It probably has to do with IPmasq. I got 500's (Illegal PORT command) all the time after moving my dialup to the linux box and setting up masquerading. I have two suggestions: 1) Try running FTP in passive mode. This forces the client to initiate the connections, which masquerading allows. Once I had my FTP clients (whether Linux or Win9X/NT) running in passive mode, FTP worked fine. 2) Look into the ip_masq_ftp module in the kernel (it's experimental). Installing this module should let you run FTP normally (it did the trick for me). You'll have to set the kernel config to prompt for experimental drivers and then look in the networking section if you use menuconfig or xconfig. You'll also need to load the module by hand (or specify it to load at boot time), as I haven't seen it get loaded by the kernel yet (running 2.2.10 kernel). Good luck!
