See the second screenshot, please? Under the title "Create Interface", there
is a column where the letters "MULLVAD_VPN" are written. Here, in this type
of space, we can type something freely.
Next, there is a space where the letters "Unmaneged" is written on the middle
of the example of LuCI interface. Here, we cannot type something into freely.
Because if you click the space, kind of popup appears and you can choose one
of them by clicking. You cannot type anything in the space, right? And I can
choose "Unmanaged" according to this instruction without problem.
Next, there is another space, this is the subject of this thread, you can see
the letters "tun0" and kind of an icon in the space. Here, you cannot choose
anything nor type anything because even if you click on the space, or button,
nothing happens. There are other this type of buttons too on some pages of
LuCI.
There might be a space where I can type "tun0", but at least in this page,
there seems not to be such a space, right? How to handle this problem? Would
you give me a little bit of your time, please? Or should I ask OpenWRT team?
I would mind it because I know they will ignore my email, that may mean it is
waste of time. But that might be a problem of OpenWRT rather than Trisquel.
