The protocol used by a proxy-based firewall.
Possible ValuesNONE, TUNNEL, SOCKS4, SOCKS5
This property specifies the protocol that the driver will use to tunnel traffic through the FirewallServer proxy.
|TUNNEL||80||When this is set, the driver opens a connection to Greenplum and traffic flows back and forth through the proxy.|
|SOCKS4||1080||When this is set, the driver 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.|
|SOCKS5||1080||When this is set, the driver 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.|
