I've tried and tried to get an OS/2 workstation connected via the internet to see a WARP Server domain controller at another site. When I connect the OS/2 workstation to the domain controller locally via a LAN, it works just fine. TCP/IP is configured and works correctly. If I netping the server that is the domain controller from the remote workstation (when it is connected via the internet), I notice that the MAC address is all zeroes. Same thing happens when I try to netping other workstations on the same LAN as the domain controller.
