Hi Gert, thanks for the information. I see you effectively increased the size to 1.2k which, as far as I know, will not work for people with dial ups. Surprisingly, it seems there is still some 3% [1] of people having that type of Internet connection.
I wonder, if you considered this or not, or if there is a mean in OpenVPN code which will make OpenVPN work even in these case (without user interaction).
