SAP Business One Server connection

Dear All,

I am trying to connect SAP Business One 8.81 PL05 client with a remote server through a static IP medium. When installation asks for Licence server details, I provide the static IP as Licence server name and port=30000 but it shows an error that "SAP DI API installation failed". Can you please tell me that is it possible to connect client to the server through a STATIC IP? if yes, then any other thing I need to do to make the connection possible. A quick reply will be highly appreciated. Thank You
