How do I deny Particular port from particular country ?

Linux Fully Managed Dedicated Server has a full root access to customize all settings and change the required modification which you required. Its having a plugin called “ConfigServer Security & Firewall” option to restrict the incoming and outgoing connections and ports etc. By using the same option you can enable or disable particular port easily in TCP_IN and TCP_OUT option for IPV4 connections.


If you want to restrict one particular port alone from one single or specified countries you can do it using same “ConfigServer Security & Firewall“.

You can follow the below procedure for the same,

1. Login to your WHM as a root

2.Choose Firewall Configuration under csf – ConfigServer Firewall

3.Under Country Code Lists and Settings Enter the Ports which you want to deny in “CC_DENY_PORTS = ” and the exact country from which you want to disable the port in,

“CC_DENY_PORTS_TCP = ” and “CC_DENY_PORTS_UDP = ”

IMPORTANT NOTE:
———-

This option uses the same format as TCP_IN/UDP_IN. The ports listed should NOT be removed from TCP_IN/UDP_IN

By this way this option denies access from the mentioned countries to specific ports listed in CC_DENY_PORTS_TCP and CC_DENY_PORTS_UDP.
