It seems that your environment + configuration is setting the buffers to 131072 (128K). It's not clear why, but I suspect it is the remote server. In my case, since the update, my UDP tunnels have consistently been:Socket Buffers: R=[42080->42080] S=[57344->57344]Prior to the update, I had a mix of the above and the following:Socket Buffers: R=[42080->524288] S=[57344->524288]Socket Buffers: R=[524288->524288] S=[524288->524288]I don't set sndbuf or rcvbuf, but perhaps the remote server is.

I know you can add it manually under advanced configuration.... but that also states [it] is going away
And once we move to openvpn 2.6 the custom field will be gone. So there is no possible way to tweak this
