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.

Destination IP	For Route through SOCKS server, specify either a single IP address or a range of IP addresses of origin servers for which Content Gateway must use the SOCKS servers specified in the SOCKS Servers field below. For Do not route through SOCKS server, specify the IP addresses of the origin servers that you want the proxy to access directly (without going through the SOCKS server). You can enter a single IP address, a range of IP addresses, or a list of IP addresses. Separate each entry in the list with a comma.
