Me and @p4bl0. I've got one box with ssh on 22. Logs are very noisy and the rules from fail2ban grow and grow.

On the other 20+ boxen with ssh on port xxx22 the logs and f2b rules are much smaller - which means less hassle for the admin.

And on the boxen with services behind WG there is zero noise.

Naturally we're using keys only with all this. The reduced noise in the logs/rules/firewall are very handy.
