AZTCOFW / TECHNICAL GUIDE
Troubleshooting FTP Connections
In AZTCO-FW software versions 2.0.x and 2.1.x, the FTP proxy is in -kernel. The only options to control its behavior are an on/off switch and a list of ports to be used by the proxy.
In AZTCO-FW software version 2.2.x and newer, there is no built-in FTP proxy. See Using NAT and FTP without a Proxy.
