SOCKS Proxy	Enables or disables the SOCKS Proxy option. As a SOCKS proxy, Content Gateway can receive SOCKS packets (usually on port 1080) from the client, and forward requests directly to the SOCKS server. For more information about the SOCKS Proxy option, see Configuring SOCKS firewall integration. If you change this option, you must restart Content Gateway.
SOCKS Proxy Port	Specifies the port on which Content Gateway accepts SOCKS traffic. This is usually port 1080. If you change this option, you must restart Content Gateway.
