Connection Modes: Direct and Proxy
About Connection Modes
CC-SG offers three connection modes for in-band and out-of-band
connections: Direct, Proxy, and Both.
• Direct mode allows you to connect to a node or port directly, without
passing data through CC-SG. Direct mode generally provides faster
connections.
• Proxy mode allows you to connect to a node or port by passing all
data through CC-SG. Proxy mode increases the load on your CC-SG
server, which may cause slower connections. However, Proxy mode
is recommended if you are more concerned about the security of the
connection. You need to keep the CC-SG TCP ports 80, 8080, 443,
and 2400 open in your firewall.
Note: Beginning with CC-SG 4.2, proxy mode supports encryption of
KVM data when using Dominion KXII release 2.1.10 and higher. In
this configuration, KVM data is encrypted according to the security
setting in the KXII device. Encryption is not supported with devices
other than Dominion KXII 2.1.10.
•
Both mode allows you to configure CC-SG to use a combination of
Direct mode and Proxy mode. In Both mode, Proxy mode is the
default, but you can configure CC-SG to use Direct mode when
connections are made using client IP addresses in specified ranges.
Note 1: When CC-SG is in Proxy or Both mode, you can give users
access to virtual media on KXII devices. However, users can only
use VKC in Proxy or Both mode. MPC is not supported in Proxy
mode.
Note 2:
Some interfaces only work in Direct mode even though you
configure CC-SG to use Proxy mode. These interfaces include ILO,
RSA, DRAC, Web Browser and VMware Viewer. See
About
Interfaces (on page 78).
