Error Connecting DB2 DB from .Net application

I get the below error when I try to connect to DB2 DB from .Net application

No matter what connection I use (ODBCConnection, DB2Connection), I get this below error

SQL30061N The database alias or database name "XXX " was not found at the remote node. SQLSTATE=08004

I think that's TCP/IP error. Is a port on the server set up for listening? Is there some firewall blocking that port?
