So, if I understand properly you have a PC with AmigaForever and WinUAE connected via ethernet to a real Amiga. The AmigaForever software provides a utility called Explorer that allows you to see the drives on the Amiga from the PC, but this does not appear to be working although the Amiga and the PC can ping eachother.
I just want to make certain that you have the explorer software running on both the PC and the Amiga. I did not do this the first time I tried to hook up an Amiga and PC. The Amiga version of the Explorer program must be running before any connection can be established.
