CSF not Allowing Ports !!!

Hello, My CSF does not Allow ports that listed in "Allow incoming TCP ports". When I add a port in TCP_IN and TCP_OUT fields, and then saving changes and restarting lfd, Port will be open for a few seconds during restart, but it will be useless upon restart finished. It made me really confused! Any suggestion ?

How are you restarting csf? Is testing mode enabled in csf conf? How are you making sure that the ports are not open?

I guess you think I'm a newbie, But I'm not. I know how to restart CSF/LFD. I do restart lfd from CSF interface in WHM. Ofcourse testing mode is not enabled. This port is used for a payment gateway. As payment gateway says "could not connect to host" so there is some problems with server. As I mentioned in previouse post, problem willbe fixed during restart but after that, port will be blocked again and all connections will be refused.

Have you flushed CSF?

Try add the IP to the allow list and restart !

Hey, Try to add iptables rules in the file /etc/csf/csfpost.sh to open your ports and restart csf. vi /etc/csf/csfpost.sh and add iptables -I INPUT/OUTPUT -s 0/0 -p tcp --dport -j ACCEPT Use INPUT for inbound connection and OUTPUT for Outbound connection.

Problem has been fixed. Connections to that port was refused because there was no service running on that port.

A very bad idea ... CSF provides neater ways of doing these things. Like adding a line to csf.allow or adding a port to TCP_IN etc.

Right, there was no problem with the way you allowed the port but a service should be running on the port to respond.
