the virtual VPN adapter of Barracuda VPN client should be set on first position (as is default setting), e.g. to permit internal DNS resolution.
On some occasions, this automatic priorization doesn´t work. Affected clients are from different customers, different OS versions, installed software etc., we cannot see any outstanding common setting.
Barracuda support tells us to ask Microsoft why Barracuda client cannot set the metric as configured.
Unfortunately, I can´t really do that, so I wonder if other users have found a solution to this issue?
Currently, we´re manually setting the metric, might be done by GPO.
