Fail2Ban configuration of OpenVPN

Is there any way we could get Fail2Ban to work with openVPN?
 
My configuration to make it work is below however some of the following files get overwritten each time FreePBX is restarted.
 
-----------------------------------------------------------------------------------------------------
 
/etc/fail2ban/jail.local  Add:
[openvpn]
enabled  = true
port     = 1194
protocol = udp
filter   = openvpn
action =  iptables-multiport[name=openvpn, protocol=udp, port=1194]
        sendmail[name=OpenVPN, dest=[Replace with email address to notify], sender=[Replace with Senders Name]
logpath  = /var/log/openvpn.log
maxretry = 3
 
-----------------------------------------------------------------------------------------------------
 
/etc/fail2ban/filter.d
   Create file openvpn.conf (only needs to be done once)
   Contents:

1. Fail2Ban filter for OpenVPN rejections

   /etc/openvpn/sysadmin_server1.conf
      Add line:
   log /var/log/openvpn.log
    
   -----------------------------------------------------------------------------------------------------
    
    
   /etc/sysconfig/iptables
     (I believe this only needs to be done once)
      Add lines:
   :fail2ban-openvpn - [0:0]
   -A INPUT -p udp -m multiport --dports 1194 -j fail2ban-openvpn
    
   -----------------------------------------------------------------------------------------------------
    
   Logrotate already has a fail2ban configuration that is attempting to rotate /var/log/openvpn.log, so nothing needs to be done for rotation.
