The protocol used by a proxy-based firewall.
Possible ValuesNONE, TUNNEL, SOCKS4, SOCKS5
This property specifies the protocol that the connector will use to tunnel traffic through the FirewallServer proxy.
|When this is set, the connector opens a connection to FTP and traffic flows back and forth through the proxy.
|When this is set, the connector sends data through the SOCKS 4 proxy specified by FirewallServer and FirewallPort and passes the FirewallUser value to the proxy, which determines if the connection request should be granted.
|When this is set, the connector sends data through the SOCKS 5 proxy specified by FirewallServer and FirewallPort. If your proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes.
