[Solved] Disable/enable TAP-Windows before connect (on pre-up)?

Post by pavelvpn » Thu Aug 23, 2018 3:26 am

Hi all,

I've noticed that, sometimes, on some Win7 machines the client connection faults out after numerous "Waiting for TUN/TAP interface to come up" messages.
I resolve it by manually disabling and re-enabling TAP-Windows Adapter, or restarting the system.
Is there a way to run a pre-up script that would reset the adapter before attempting to connect?

Currently I use

Code: Select all

up up.bat
where up.bat is

Code: Select all

ipconfig /renew *
that seems to solve the problem 80% of the time, however it doesn't seem like the right solution for the problem.

There are specific options for that.

See --tap-sleep, --dhcp-renew & --register-dns in The Manual v24x
