Wordfence is an awesome plugin, I believe the best security plugin out there...however, one area I always struggle with is the optimum settings for the FIREWALL and LOGIN sections. Everything else is straightforward but get these two areas wrong and you create problems for yourself.
I have scanned the net for tutorials and how other users set these two areas up but so far I can't find anything that discusses throttling values for humans or bots. Likewise it' hard to find anything definitive on login attempts, lockout durations, failure counts etc.
The LOGIN area is probably more of a personal preference and I can play with those settings without doing too much damage but the FIREWALL section is something I would like more clarification/advice/tutorials on.....anyone?
