Hi,
I just noticed a possible new bug that appeared with the new version of openvpn server 2.3.2 on windows server 2012. I'm posting it here before putting in a bug report to see if anyone has had issues with this.
The problem occurs when openvpn sends some form of network command through a bridged TAP adapter. This causes a BSOD pointing to the windows driver bridge.sys. This is the same problem as many many people are having when using bridging to bridge their lan and hyper-v network adapters (see here
http://henkhoogendoorn.blogspot.co.uk/2012/09/bsod-in-windows-8-on-bridgesys-driver.html for example, there is a much longer technet thread as well, but can't seem to find it now.)
Returning to openvpn version 2.3.1 solves the problem, no more BSOD.
Has anyone had this issue ? The Microsoft bridge.sys driver is effectively buggy, but perhaps we might be able to determine what causes it to crash by looking at what changes were made between 2.3.1 and 2.3.2.
