If that's all that's in jail.local, then the jail shouldn't be enabled.  
They're off by default.  I'd suggest that you remove fail2ban 
completely.  Remove the packages, and then delete /etc/fail2ban, and 
start again.

When you're done, look at the output of "iptables -n -L INPUT_direct":

# iptables -n -L INPUT_direct
Chain INPUT_direct (1 references)
target     prot opt source               destination
REJECT     tcp  --   match-set
