OK DDNS should work with proper VPN Policy setting (only allow VPN for certain IPs)
But in case of the issue with the OpenVPN Client and a simultaneous Wireguard connection you should reconsider your “design” because in this case your device will not suit my requirements/ use case.
As this is something which is in direct regards to the GL.Inet UI you might think about changing this restriction because it is useless and reduces the functional range of the device…
to be honest, I bought the BRUME just for exact this use case because I thought this device can handle my needs withe ease.
