PPTP not connecting from Windows guest in 6.0.4

[pkx232c]

Hi,

Running Virtualbox 6.0.4 on Windows 10 x64 host, guests cannot connect to PPTP VPN. Tried with both Windows 7 x64 and Windows 10 32bits guests.

Connection hangs at "checking username and password" and finally disconnects with "Error 734: The PPP Link Control Protocol Was Terminated"

Downgrade to 6.0.2 solves the issue, guests can connect again to PPTP.

Using bridged networking :-)

I will be happy to provide any log or test you may need.

PKX.

1. It's usually better and faster, if issues get first addressed in the ​VirtualBox forums, a lot more eyes there. More than 95% of the issues are resolved in the forums, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of. For example, yours is most probably not a bug and someone from the developers has to deal with it and close it as "Invalid".

Plus a discussion and analysis on the bug tracker is going to help you, me, and potentially a future drive-by user or two. Not so in the forums, many more tend to benefit...

So, if you can, please open a new thread in the ​VirtualBox on Windows Hosts section of the forums. Please be sure to mention that you came from the bug tracker and include the ticket number.

2. You were supposed to follow these steps when you filed the bug, and provide a VBox.log:

   Attach a (full) log file ("Machine" menu/"Show Log" in the main VirtualBox Manager window) straight away to save time for you and for us. The log file contains a lot of useful information about both the host and the guest systems as well as information about what happened during a particular machine run. Please do not cut and paste it.

Are you bridging to an Ethernet or to a WiFi adapter?

Please, can you provide packet capture from the guest for the failed PPTP connection.
