Linux environment

First, verify that the management and data ports for your firewall are open so that the BC Interior server uses to communicate with the Gateway Server. 

For more information please refer to Figure 4 showing the Gateway Server and Interior Server communications in "Chapter 2  TIBCO BusinessConnect Architecture : Interior Server and Gateway Server Architecture" of the Business Connect concepts user guide. 

The Administrator server should have access to the management port.  Make sure you are able to connect from your admin server to the gsengine on management port by running the telnet command.
