Configure a Combination of Direct Mode and Proxy Mode
When you configure CC-SG to use a combination of Direct mode and Proxy mode, Proxy mode will be the default connection mode, and Direct mode will be used for the client IP addresses you specify.
To configure a combination of direct mode and proxy mode:
Choose Administration > Configuration.
Click the Connection Mode tab.
Select Both.
In the Address field enter the IPv4 or IPv6 address, and specify the Prefix Length to create the range that should connect to nodes and ports via Direct mode. Prefix Length may be 1 to 32 for IPv4 address, and 1 to 128 for IPv6 address.
