BYD / HANA System DNS Connection

I'm trying to establish a connection from Crystal Reports into a Business ByDesign Tenant. In doing some research, it was recommended that I install Microsoft ODBC Administrator, which I've done. The next step is to configure the DNS server settings, as shown below. Would anyone be able to help? I think I know where to place the tenant host information, however dont know how to attain the tenant port number.
