Re: fail2ban increase loadaverage to 18

connlimit - allows you to limit the number of simultaneous open 
connections to each IP-address (or subnet).

/iptables/sbin -p tcp -syn -dport 22 -m connlimit -connlimit-above 3 -j DROP

this command allows up to three simultaneous connection requests to our 
ssh-server with one IP-address.
