Remote access to a Netware 6 FS

Hello, I have a Netware 6 w/latest SVC Packs and running fine. I have implemented what I beleieve was the required SW to access it via the Internet, same set of Sw as in NW5, however, I can’t get to it, IT IS NOT an IP or connection problem, it seems that not all required Sw may be runnign on the Server, Any guidelines as to what the SW should be for remote access to a NW6 server?

Thanks
