Appendix C: CC-SG and Network Configuration

CC-SG Internal Ports

CC-SG uses several ports for internal functions, and its local firewall

function blocks access to these ports. However, some external scanners

may detect these as “blocked” or “filtered.” External access to these

ports is not required and can be further blocked. The ports currently in

use are:

• 1088

• 1098

• 2222

• 4444

• 4445

• 8009

• 8083

• 8093

In addition to these ports, CC-SG may use TCP and UDP ports in the

32xxx (or higher) range. External access to these ports is not required

and can be blocked.

CC-SG Access via NAT-enabled Firewall

If the firewall is using NAT (Network Address Translation) along with PAT

(Port Address Translation), then Proxy mode should be used for all

connections that use this firewall. The firewall must be configured for

external connections to ports 80 (non-SSL) or 443 (SSL), 8080 and 2400

to be forwarded to CC-SG (since the PC Client will initiate sessions on

these ports).

Note: It is not recommended to run non-SSL traffic through a firewall.

Connections using the firewall must be configured to use Proxy mode.

See Connection Modes: Direct and Proxy. CC-SG will connect to the

various targets on behalf of the PC Client requests. However, the CC-SG

will terminate the PC Client to Target TCP/IP connection that comes

through the firewall.
