No ! Not at all
When I log out I´m returned to my homepage ( as a second brute-force attack) not to my admin-Log-in page (as normally) And immediately I´m blocked.
The free adminexile was in a way much better. I could block an Ip for e.g. 5000 min, penalty x100 and brute force attack number to 1 try. Meaning, I got rid of that ip for a very, very long time
Of course I could put my ip-address at the white-list.
I wonder why this is happening and if there are some more problems I´m not aware of right now.
Looking forward for more advice
I have a test version that's working in J4 alpha. When the beta version is released I'll do more testing - but yes, I plan on making all of my extensions J4 compatible when a release version gets a little closer.
