in the firmware RUT9_R_00.07.00, the OpenVPN "extra options" fields will not allow spaces to be entered. Hence, things like "remote xxx.xxx.xxx.xxx" for a second remote server cannot be entered.
Really, no options requiring parameters can be entered via the gui.
Changing the config via console is ok, but the GUI will not let you save anything afterwards.
Also, Additional HMAC authentication does not do anything. tls-auth parameters must be added to /etc/config/openvpn manually.
A fix would be appreciated!
