Bon voila je me précise un peu voici ce qu'ils me mettent quand je fais un test des ports :
Starting TCP connection test...
TCP test failed! UDP test will not be performed.
Connection test finished.
--------------------------------------------------------------------------------
Results in detail:
TCP connection test failed.
It was not possible, to establish a TCP connection to your eMule.
Other users will only be able to connect to you with the help of a server, resulting in a low ID for you. While eMule still works, this will give you several disadvantages. Therfore it is highly recommended to solve this problem.
