Hello, This is quite a begginner question. I have a workin peer-peer wrapper class for DP8. Before I used flags OKTOQUERYFORADDRESSING (EnumHosts() and Host()), but now I managed to set up address correctly myself using IDirectPlay8Address::AddComponent(). My question is just the meaning of ports. DP never asked any port values and now when I setup address myself, I don''t need to se ports. I can set the port value for DirectPlay8Address, but it''s not needed. Does DP use some default port or does it use all available ports?
