I have two linkstation live, each one behind a router, all the required ports are open but the file transfers are stuck and cannot complete.
What is really weird is the fact that all the protocols are concerned : FTP, rsync, and HTTP.
I can connect ssh between the two linkstation and the transfers are initiating correctly, but stuck if the file is larger than 100Kb approximately.
What is more than weird is when I connected the two linkstations on the same router and tried FTP/rsync/http transfer on the local ip, the same problem occurred, conclusion: this is not a problem related to the network configuration, nor a software problem, since the two linkstation can download a file hosted on the Internet or on a local machine, but definitely not when this file is on the other linkstation.
When I installed the second linkstation, I made a raw copy of the first linkstation hard drive with dd, can this have a relation to this problem ?
Any idea ?
