I have added the Ip's to vi /etc/fail2ban/jail.conf as below

ignoreip = 127.0.0.1/8 161.47.34.7/32 173.203.2.22/32 108.166.43.128/32 204.232.172.40/32 146.20.86.8/32

But

The IP's are listed again in the IPtables

Chain f2b-postfix (1 references)

RETURN     all  --  0.0.0.0/0            0.0.0.0/0           

How can I fix this permanantly.
Thanks
