The submitted IPv4 Tunnel Network is already in use.
-
I have noticed that the Copy Open VPN Server option has some additional validation to check that the Tunnel Network does not conflict with any other OpenVPN server configuration. This is a good idea, but I have stumbled on an edge case:
I have a disabled OpenVPN instance
I would like to copy this instance, make some changes and enable the server for testing without losing the original configuration. Specifically I am testing certificate changes.When I attempt to save the 2nd instance i get the validation error:
"The submitted IPv4 Tunnel Network is already in use."
I think this is related to Feature 3244
The validation doesn't account for the fact that the other instance is disabled.
This feels like an unintended "feature".The workaround is to change the tunnel network of either instance to something different to avoid the conflict/validation error/feature.
