Firewall Requirements
Overview
CommNet Server
CommNet Agent
CommNet Browser
The system communicates across firewall(s) using the same ports used by
the CommCell(s)/QSMCells to communicate across firewall(s). Both one-way
firewall and two-way firewalls are supported.
NOTES
- The system uses a secure proprietary protocol for
all inter-process communication on enabled ports.
Consider the following to ensure the smooth operation of the system
across firewall(s).
Communicating with a CommServe
- If the CommNet Server is installed on a computer which has the CommServe software installed, the
same firewall ports are used by both the CommServe and CommNet Server.
- If the CommNet Server computer behind a firewall does not have the
CommServe software, you must install the SQL Server
iDataAgent. (The SQL
Server iDataAgent is also required to backup the
CommNet Server database to provide disaster
recovery solutions for the CommNet Server.) Note the following:
- The firewall ports used by
the SQL iDataAgent are also used
by the CommNet Server.
- If any CommCell in the CommNet domain is
configured to communicate with the CommNet Server across a firewall, the
Bull Calypso
Communication Service must be running on the CommNet Server computer.
- If the CommNet Server and the SQL iDataAgent
are installed using two different interface names, then the CommNet Server and
the SQL iDataAgent must be
installed with the same interface name. For example, if the CommNet
Server
is installed using computer1.company.comthen the
SQL iDataAgent must also be
installed using computer1.company.com.
Communicating with a QSM Server
- In order for the CommNet Server to communicate with a QSM Server across a
firewall, the port used on the QSM Server must be allowed connection across
the firewall. This port number is defined in the QSMCell GUI Server Port Number
field of the Register CommCell/QSMCell
dialog box.
As the CommNet Agent is installed on the CommServe computer, the firewall ports
used by the
CommServe software will also be used by the CommNet Agent.
If the CommNet Browser is installed as a stand-alone application, (without any
other CommServe component on that computer) and if the computer is across firewall(s) from the CommNet Server, port number 8403 must be allowed
connection through the firewall.
If the CommNet Browser is opened as a remote web-based application, then
in addition to allowing connection for port 8403 through the firewall, ensure
that the http service port, which is typically port 80, is also allowed
connection in the firewall.
