Need port range to open firewall rule  

You have the NMS Services LPAR and WebLogic LPAR on different subnets.

The NMS managed server couldn't be started and you see the below error in the WebLogic managed server log:
Testing the following initial reference
Testing corba name service port
Testing port NamingService
Resolving host: <server>
  Resolved to <server>/<IP address>
Testing socket on port 17820
Attempting to narrow...
Attempting to resolve InterSys_nmsadmin
Testing port InterSys_nmsadmin
Resolving host: <server>
  Resolved to <server>/<IP address>
Testing socket on port 37750
com.splwg.oms.ejb.ConfigException: InterSys_nmsadmin is not listening on port 37,750 on <server>.  Verify that the correct port is configured

You ran this command and get the intersysobject ports from the NMS Services LPAR:
>tao_nslist -ORBInitRef NameService=iioploc://<server>:17820/NameService
Naming Service:
+ intersysobject: Naming context
| + InterSys_nmsadmin: Object Reference
| |   Protocol: IIOP
| |   Endpoint: <server>:37750
| + InterSys_nmsadminPublisher: Object Reference
| |   Protocol: IIOP
| |   Endpoint: <server>:37749


According to Solution #2 of Oracle Knowledge article "Corba.Comm_failure When Attempting to Access NMS Application (Doc ID 1318075.1)", you should open firewall rule for the ports used by the intersysobjects.

1) What is the port range used by the above intersysobjects?
2) Are the port ranges for these objects customizable?
