@xupetas, I have encountered the same problem as you after creating an OVPN server. Port reflection is not working when a user is connected to OVPN. However, the workaround is working like a charm. Thanks for the information.
The 'do not add/remove route' option in the new instances setup method is under the 'Miscellaneous' section > 'Option' > 'route-noexec'.
