I have been working with GTS Enterprise for 4 & 1/2 years, so I'm sure I can finish configuring the system for you.
I do have a couple of questions:
1) What OS are you running GTSE on?
2) What version of GTSE are you using?
3) What are the makes & models of the devices you are using?
Most of what you have described in the project description will be implemented by making changes to the configuration files.
These issues are described in the documentation, did you rebuild, redeploy GTSE, then restart Tomcat and the DCS's?
Also check the firewall, and make user the port(s) your devices are using is not blocked.
