Ok I've probed port 47624 which is directx7 connection port and it is also open. 6073 is for directx8 which is closed so I believe dbpro must be using dirextx7 connection method and is using port 47624. Either that or I may need to open 6073 but anyway can you check that port is open on your end.
I get the same port numbers showing up on my zone alarm, not sure what the story is with port 1900, but I'm not sure how to open it or if I should or if it's even to do with it. (btw i have my zone alarm off while testing here)
What connection are you on btw cellbloc? 56k, dsl faster? Don't think it matters but just to know.
[edit] Like NewbieBrogo tested for me online a while ago and he could connect and chat etc. So I'm sure it works but it's good to get an understanding of what is going on with the ports and stuff to make it easy for as many people to connect. Plus it would be great if you could finally connect cellbloc
I can keep the server up for about another hour or 2 then i will have to go.
