I’ve successfully uploaded the .ovpn file to my AR300M.
I’m just using default settings on both my Asus RT-AC68U and my AR300M.
I’m getting “Failed to open tun/tap interface”
“–cipher is not set”
“Previous OpenVPN version defaulted to BF-CBC as fallback”
I’m not sure where to go from here. Looking at the System Log on the router doesn’t show anything that’s helpful from what I can tell.
My OpenVPN Server port is 1194, and my RSA Encryption is 2048 bit.
