What can I do? csf do not let OpenVPN go outside,?

“The critical problem is caused by some packet filtering tool blocking UDP or OpenVPN:

. 2022.12.06 19:19:06 - OpenVPN > write UDPv4 [ECONNREFUSED]: Operation not permitted (fd=7,code=1) . 2022.12.06 19:19:07 - OpenVPN > write UDPv4 [ECONNREFUSED]: Operation not permitted (fd=7,code=1) . 2022.12.06 19:19:12 - OpenVPN > write UDPv4 [ECONNREFUSED]: Operation not permitted (fd=7,code=1)"

Hi, I just to inform you that I installed it on my mobile PinephonePro with Mobian (Debian adapted) and installed it very well. Neither UFW nor the other one you mention to stop could be installed. I would like to know if my mobile phone is quiet enough as installed by default or if should I modify something. I can send you any log you need for you to see how was installed...

In reply to dragonmouth.

@Dragonmouth,

I stopped and disabled firewalld on the system, as CSF is more powerful than default firewalld, as it provides better Login/Intrusion Detection and Security feature with easy to use interface for managing firewall settings on your Linux server.

It’s up to you, whether you want to remove or disable..

If you are running FirewallD already, why install CSF unless you want to replace FirewallD? In the article you never uninstall FirewallD. Please explain your reasoning.
