VPN connection times out when trying to move big files

Post by soojendi » Sun Jul 02, 2017 1:38 pm

Hei,

I have a problem that when i try to copy big files(around >1GB) then at random point the process just stops. Speed drops to 0 bytes and eventually it times out. Strange is that after timing out the vpn connection disconnects also. And after connecting again most cases it still wont be able to access the NAS file shares. Then only thing what helps is to restart the client computer.

I have tried setting the MTU's lower on the client side but thats no help, also tried both UDP and TCP protocols and everything is still same.
I have tested this on 3 different Windows 10 computers and the result is always same.

Can anybody please help me?
