Issues Configuring CSF Properly

[Lexy]

Hi everyone!

Plase help! I started to set up CSF Firewall to protect server from attacks and to gain max. score of protection. After this tuning the receiving of e-mails from root and external scripts disabled. Moreover, the process of loading the web-sites which refer to my server have become incredibly long. To what mistake it could refer?

Thank you in advance.

Hi,

I would like you to check 2 logs on your server when the CSF is enabled:
1. Apache server error logs.
2. LFD alert logs..

Apache server logs will help you analyze if any web firewall is blocking it or not like modsecurity and lfd alert will actually tell you if it blocked anything related to modsecurity..

Thank you for the answer.
Could you please explain how can I find these error, alert logs?
All e-mails that should be sent via system are displayed in Mail Queue Manager,
but not send even if I try to deliver it from there by myself.

Hello,

Please keep in mind that CSF is a third-party application. I recommend posting on their support forums for help setting up the firewall rules:
