currently i am facing a strange issue and i believe it is related to the Asus RT-NU18 which i would like to use as i client.
This Router is using OpenVPN Client Version 2.3.2. To crosscheck i have installed an GUI on Windows(Version 2.4.4) and on Linux(2.4.6). Both created a connection successfully.
Furhter i have extended my testing by using a --nonpass configuration with an additional ovpn file which creates a connection even with my Asus...
