Thank you for the clarification and for keeping this thread open.
You are right that I mentioned this request earlier in other discussions. In fact, it has been almost three years since I first raised this topic. Over that time, I asked about this feature in a few different contexts (for example in router-specific threads like Flint 2 / Flint 3 and also in a firmware discussion), because originally my question was related to those particular devices.
However, over time it became clear that this is not really a router-specific question, but rather a general feature request related to GL.iNet routers that support both Multi-WAN load balancing and VPN client connections.
Looking back, it was probably not the best approach to ask about it in several device-specific or firmware threads, since the request became scattered across different discussions and therefore did not get much visibility. That is why I decided to open this separate feature request thread, so the topic can be discussed in one place and the actual demand for it can be seen more clearly.
I believe this functionality could be very useful for users who rely on multiple WAN connections for redundancy while also wanting VPN protection on all active connections.
If anyone else would benefit from this feature, it would be great if you could share your use cases here as well. That should help the team better evaluate the demand.
Thanks again for taking the time to review this request.
