We've defined two IPsec-tunnels to remote networks (/24). It seems that If one of the connections can't be established (for example due to authentication failure), the other one will not come up, too. So it's all (VPN) or nothing after starting the device.
If both tunnels are established, the failure of one tunnel will NOT break the other one, so this is correct behaviour.
Seems to be a bug? Or how can we prevent this?
Beside of this it's a great device :-)
