Inbetween, I have a router which is running standard Kernel 3.8.13 and provides NAT (Masquerade) to the PC. Reading the directory and a first file from the PC works well. But when trying to read a second file, the router stops forwarding the packets from the server back to the masqueraded PC. It was working well with Kernel 3.7.10 It still fails with Kernel 3.10 Is there any change between 3.7 and 3.8 which could explain it ? How can I investigate this problem ? Christophe
