in general : Someone correct me if im wrong but XDCC is a fileserver concept, when it comes down to the actual send its just a dcc send so if you can recieve from xdcc bots you can recieve from anyone, its just if there configured ok, and your configured ok, such as has been just mentioned, use random ports , sometimes one port in the random list doesnt work, so you can get odd fails out of the blue, which can leave you scratching your head.

Riamus2 : Yes you were right about ports shouldnt matter really if you can recieve, I think i had forgotten he said he can recieve at some point (or he changed his mind and said now he cant recieve at all, i cant remember)
