L2TP/IPSec connects but instantly disconnects

Fri Sep 13, 2019 6:55 pm

Hi All

As per the subject line, I've set up a VPN link from my Windows 10 PC to a Mikrotik router (via WAN of course). As I have enabled L2TP and IPSec logging I can monitor the connection and from what I can tell it goes through the whole initiation and establishes a connection only to instantly disconnect again.

The log shows "succeed" and then the next line is delete payload for protocol ISAKMP and then there are a few purges and deletes and no connection. Windows just says connection can't be established, you might need to change network settings etc.

Any ideas?

Thanks,
R

It seems to be something specific to my Windows 10 machine. Tried the exact same config on my Windows 10 laptop and it connects without an issue. I've tried the "Network Reset" (in Windows 10) but it still does the same. I suppose a reinstall is now my only hope.
