Hello Polina,
I tried exactly to your description to enter a whitelist in V. 6.10.xx and V 6.12Beta4.
It is identical in both versions. I cannot distinguish between "Whitelist" and "Blacklist"-tab no matter if ich sel ect "Allow everyone, except" or "Deny everyone, except". I installed on 4 different machines now, always the same result! Every IP-address or IP-range ends up in "Allow everyone, ..."
I also tried to install an english version of the host, but I always end up with a german version.
And that seems to the point of it. It seems to be
a language problem!
The two tabs for "Blacklist" and "Whitelist" are
not klickable, as you can see on my screenshot. Instead, there is
just the text and a "
\n ;" between "Blacklist" and "White list", "Blacklist" is not seperated by a space, like in your screenshot.
To me, this whole issue look like a bug in the german version ...
Like I said, I installed the host on different machines, new and older Win10pro-installlations, all the same.
Looking forward to hearing fr om you,
Kindest, Klaus
