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?
