As per subject, last update v5.77 (even v5.76) only allow whitelisted ip in csf.allow to contact the server. I got this issue on 2 servers running plesk and a custom kernel from ovh.
Hope someone can provide further support about this issue.
Regards in advance.

Re: CSF forwarding only whitelisted IP
You will need to run the following from now on for csf until your provider fix their broken custom kernel:
Code: Select all
sed -i 's/-m conntrack --ctstate/-m state --state/g' /etc/csf/csf.pl
