If I select Virtual Switch mode, I get no external connectivity by TCP/IP or NETBIOS but local >>>connectivity (to the host), including NETBIOS, works. It seems (easy for me to say) that this is a Prism driver >>>issue, rather than a VPC issue. Followup: Now I'm REALLY confused. I decided to play around with Shared Networking (NAT) mode in VPC over the WiFi port, again. This, even though the VPC docs tell you it is limited in what you can do through it. WELL, since going through all of the gyrations to get full access to my LAN when using the Intel hardwire ethernet port (VPC running Win98SE), I have somehow achieved virtually the same level of function using Shared Networking (NAT) mode! >From VPC, I am able to access shares on its host computer (Thinkpad), the other OS/2 workstation on the same subnet, and SAMBA shares my Linux server located on another subnet that is physically removed from this location. The server is linked over the internet by a pair of SmoothWall firewall/VPN boxes. All TCP/IP and SMB network connections originating from VPC work. I can't access the VPC from the network, presumably because of the translation going on in the host, but as of the moment, that is immaterial since I don't intend to use my Thinkpad as any sort of server. An acceptable, for the moment at least, workaround has seemingly been achieved.
