Hello all,
after some months of testing and improving I’m happy to share with all of you the scripts and commands that I use to have a Failover and Load Balancer in my RouterOS. Thanks to all information that I find on internet (I started from Tomas Kirnak script that you can find on Wiki), and then I was happily inspired by all the other posts and page that I found.
You can find everything here:

Please feel free to comment and suggest me any improvement that can be done
