Installed successfully, but not working

[linsamy]

The CSF works after installing and activating the CSF. Test IPtables shows that everything is ok. All configuration is in default mode.

I tried to block an IP from the main screen with Quick Deny, server became inaccessible. I can't connect with putty, webmin, and all websites are down.

I can only connect through the console access provided by the hosting company, and if I disable the CSF and system goes back to its normal state.

Any guidance on what could be the problem.

Thank you

It sounds like if you have blocked your own IP, try to "flush all blocks" from CSF and try to block a complete different IP as the one that you use.

Thanks Sergio for the response.


I checked the configuration once more and noticed that I used ":" instead of "," for one of ports in TCP_IN section when separating the ports. After correcting that it now works.
