Open Port Fails

[pacogp]

Hi guys.
Thank you for support.
I was trying to open a port on 24001 but when i check with an external tool says its closed.
I have to setup anything instead of configserver security firewall?

TCP_IN="20,21,25,53,80,110,143,443,465,587,993,995,2077,2078,2082,2083,2086,2087,2095,2096,1563,6100:6200,24001"

lsmod | grep ip_tables
Opening /proc/modules: No such file or directory
