I recently installed csf on my dedicated server and installation went successfully, but when I try to add an ip address to the allow list like the following, it does not show up in the iptables. I restart csf as well and still does not.
X's = port number and ip address. This is what the iptables rule(input chain) entry looks like for that:
26 0 0 ACCEPT tcp -- !lo * 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:XXXX
The allow chain shows correctly but I am still able to access that specific port on another ip address. Not sure what's going on. Do we have to disable the linux firewall that came with the system first?
Much appreciated, thank you.
