I have a server with cpanel and cloudlinux I have noticed that after changing the firewall from csf to imunify360 I can no longer open ports on the server, can you tell me what may be happening, I have investigated and in some cases indicate remove iptables or nft as there may be a conflict, I have made different change but still can not enable ports on my service ... could you help me identify what is happening

  Hey there!  It's hard to say - are you getting any specific errors from Imunify360 that could give us more details, or do the ports simply not seem to be opened?

  Since cPanel itself doesn't manage the firewall my advice is a bit limited, but we do have details here on the basic configuration process: https://docs.cpanel.net/knowledge-base/general-systems-administration/how-to-configure-your-firewall-for-cpanel-services/

  Hi, sorry for not replying more, I was working on the server, but now I am running into a detail, I have removed imunify360 and nftables only csf is working with iptables, but now it does not take the configuration for new ports.

  I can't say for sure, as CSF isn't a tool that we make our distribute.  It seems like there is a deeper issue with the system than Imunify or CSF if neither are working as expected, so it would likely be best to create a ticket to get this examined.
