Hi, Saw the below config from tinc’s manual: UDPRcvBuf = bytes (OS default) Sets the socket receive buffer size for the UDP socket, in bytes. If unset, the default buffer size will be used by the operating system. UDPSndBuf = bytes (OS default) Sets the socket send buffer size for the UDP socket, in bytes....

...sume 100Kbps bandwidth (Send and Receive). I am not sure if I am setting the right option under its main configuration file (tinc.conf) . Will these options serve my purpose? I have set them up but the Tunnel Adapter (running on Windows) still consumes all the bandwidth available. ================ UDPRcvBuf = 12500 UDPSndBuf = 12500 ================ Regards Yazeed <yazeedfataar at hotmail.com> -------------- next part -------------- An HTML attachment was scrubbed...

There is no bandwidth limiting feature in tinc. You can use other programs to do this for you. For Windows, have a look at this page: https://superuser.com/questions/13571...
