Controller Descriptions
A controller is a software object on Remote RMM-1400 that serves as a destination
for a data bit stream. There are four types of controllers that can be configured in the
Remote RMM-1400 CLI:

Bridge Controllers
 Ethernet Controllers

OpenVPN Controllers
 Serial Controllers
Bridge Controllers
There is only one bridge controller on Remote RMM-1400. The controller is named
bridge switch
because it is a bridge that (by default) includes all four of the Ethernet
switch ports. Controller
bridge switch
can be configured to include or exclude
individual Ethernet ports.
This and the next section imply that Ethernet controllers are always on the bridge.
Ethernet Controllers
There are four Ethernet controllers on every Remote RMM-1400 model. They
represent the four local switched Ethernet ports and can be included or excluded on
the bridge controller.
OpenVPN Controllers
OpenVPN controllers use the OpenVPN software package, which establishes a VPN
between Connect SCS and Remote RMM-1400. SSL is used to manage the VPN
connection, and encrypted UDP packets are used for data transmission. Both the
management and data traffic are passed as UDP packets on a single port. The
customer’s external firewall needs to open one port to the Connect SCS for all
connected client network elements.
Connections are initiated from Remote RMM-1400, so they should have no problems
traversing the service provider’s firewalls, provided the firewalls are stateful and allow
return UDP packets. Keep-alive packets are sent by both Remote RMM-1400 and
Connect SCS to detect connection failures and to keep an active firewall state.
Serial Controllers
Remote RMM-1400 has four asynchronous serial controllers. In addition, Remote
RMM-1400 can be equipped with an EvDO or UMTS phone module. The phone is
identified as
serial modem
