Firewall rules set up

FTP-Proxy does have some issues when operating within a NAT gateway. A protected FTP server must have a routable address, and the router on the unprotected side of the gateway must have static route to it the security gateway interface address is the route. Because this is a proxy application, FTP (TCP) packets destined for external FTP servers or clients will typically have as source address the address of the interface to which the FTP-Proxy rule was applied. This shows that FTP-Proxy employs some internal address translation.

Note:

FTP-Ctrl, Active-FTP, Passive-FTP, and FTP-Proxy services are intended for use with the ‘keep-state’ firewall rule option.
