Description : <\/strong><\/p>\n

A firewall is a network security system either hardware- or software-based that uses rules to control incoming and outgoing network traffic.<\/p>\n

Firewall hepls to protect (a network or system) from unauthorized access.<\/p>\n

There are two types of firewall.<\/p>\n

1. Filtering Firewalls<\/strong> – that block selected network packets.<\/p>\n

2. Proxy Servers<\/strong> (sometimes called firewalls) – that make network connections for you.<\/p>\n

The role of a firewall<\/strong> is to prevent malicious traffic<\/strong> reaching the resources that it is protecting.<\/p>\n

Some security experts feel this is an outdated approach to keeping information and the resources it resides on safe.<\/p>\n

They argue that while firewalls still have a role to play, modern networks have so many entry points and different types of users that stronger access control and security at the host is a better technological approach to network security.<\/p>\n

We can see in below steps how to block\/unblock IP address in csf firewall.<\/p>\n

Step 1 : <\/strong><\/p>\n

Login to your WHM using domainname.com\/whm using root<\/strong> credentials.<\/p>\n

Only root privileges can have the access to m<\/p>\n

\"\"<\/p>\n

Step 2 : <\/strong><\/p>\n

After logged in enter firewall<\/strong> in search box.<\/p>\n

Then click => \u201cconfigServer Security & Firewall<\/strong>\u201d<\/p>\n

You can also find the option under Plugins.<\/p>\n

\"\"<\/p>\n

Step 3 : Allow IP address<\/strong><\/p>\n

Under csf<\/strong> – ConfigServer Firewall you can find Quick Allow<\/strong> field.<\/p>\n

\"\"<\/p>\n

Enter the IP Address<\/strong> in Allow IP address field<\/p>\n

We can also update the reason \/ comment for allowing IP address in Comment for Allow<\/strong> field.<\/p>\n

Step 4 : <\/strong><\/p>\n

Once finished click => Quick Allow<\/strong> option for making changes.<\/p>\n

\"\"<\/p>\n

Step 5 : <\/strong><\/p>\n

Now the IP we have entered is added to the Firewall Allows IP\u2019s.<\/strong><\/p>\n

Step 6 : Block IP address<\/strong><\/p>\n

Enter the IP Address in Block IP address<\/strong> field.<\/p>\n

\"\"<\/p>\n

We can also update the reason \/ comment for allowing IP address in Comment for Allow<\/strong> field.<\/p>\n

Step 7 : <\/strong><\/p>\n

Once finished click => Quick Deny option<\/strong> for making changes.<\/p>\n

\"\"<\/p>\n
