CSF csf.ignore and csf.allow questions

Hey great forum and I love reading daily. I have a question regarding CSF Firewall and adding IP's to the csf.ingore and csf.allow files. What I need to do is add my ip and a few others to these two file but as to the formating of the IP is my question. Depending on what tutorial I read the IP format is different. Some people say just add the Ip like tcp|in|d=22|s=00.00.00.00.0 but other tutorials just show adding the IP like 00.00.00.00.0 without the other tcp|in|d=22|s= stuff Can anyone advise me as to the correct formatting of putting a ip in these lists? I was reading and found that a easy way to add a IP to the block list is to just csf -d 000.00.000.0 and it will add the ip to the deny list. and when it does so the format isn't tcp|in|d=22|s=00.00.00.00.0 or something like that it is just the IP any clarification would be awesome

  The advanced format is for blocking the IP only from a certain port. Normal format is to just have the IP in csf.deny which blocks it from the server entirely. The same advanced syntax can be used to open specific ports for certain IP addresses as well. Adding an IP to csf.allow normally opens all ports to that IP address. Adding an IP to csf.ignore simply allows the IP to be ignored from brute force detection (LFD) without opening up the extra ports.

  Hello :) This is documented under the "Advanced Allow/Deny Filters" on the CSF readme document:

  Thank you. Only thing is they say " you can add more complex port and ip filters using the following format" tcp/udp|in/out|s/d=port|s/d=ip|u=uid So they said this is is just a optional formal if you want to? other wise just adding the IP in both files is fine?

  Thanks for clearing this up. I am just getting the hang of this and dont want to mess up on something this important.
