Two pc's:
1 - router

Situation: someone tries to bruteforce into a server, and the logger
get's a log about it [e.g.: ssh login failed].
What's the best method to ban that ip [what is bruteforcig a server]
what was logged on the logger?
I need to ban the ip on the router pc.
How can i send the bad ip to the router, to ban it?
Just run a cronjob, and e.g.: scp the list of ip's from the logger to
the router, then ban the ip from the list on the router pc?
Or is there any "offical" method for this?
I'm just asking for docs/howtos.. :\ to get started..
Thank you!
Dear Vadkan,
You could use PF for this by using a table for brute forcing:

or "The book of PF" <- highly recommend (by me)
hopes it helps,
