This
guide will help you to be able to use a Plesk firewall to protect your
Plesk-enabled server from unauthorized access. Your Plesk panel comes with a
firewall, which you can configure. You will be able to create a set of firewall
rules and manage them using Plesk.
The
method for setting up a firewall is based on whether you have Plesk installed
on a Linux-based or Windows-based platform. Both methods are described below.
Linux-Based
Plesk Firewall
On
our Linux-based Plesk server, the firewall module is already installed and
configured. However, you can do the following:
·
View
and change predefined rules that control connections to the following system
services:
Administrative
Control panel
Webserver,
FTP Server, SSH Server, MySQL Server, PostgreSQL server
Mail
password change services
VPN,
DNS
By
default, these rules allow all incoming connections to these services. You have
the following options to:
·
View
and change the predefined system policies
·
Add,
change, and remove custom rules
To
locate the firewall module in Plesk, please follow the instructions below:
1.
First
log into your control panel at http://manage.myhosting.com.

2.
Once
you have logged in, please click on the Modules option under the Server
Management heading as show below. Modules are available only on Linux-based
servers. You can use this section to install or manage additional modules that
add useful functions to Plesk panel.

3.
In
the Modules section, you will find the Firewall icon.

4.
Click
on the Firewall icon. You will then see a list of predefined firewall
rules.

Allow or Restrict Access
to a Service
For
each system service, you can choose whether to allow or deny all incoming
connections or allow only connections from a specific IP/network address.
1.
Login
to your Plesk panel. Go to the Modules section and click on the Firewall
icon. Now click on the Edit Firewall Configuration icon.

2.
To
edit an existing system service rule, click on the service name you want to
edit and you will find options to Allow, Deny, or Allow from
selected sources, deny from others. You can make the necessary modification
and click on OK to finish the process.

Manage System Policies
System
policies define what is done with all incoming, outgoing, and transit
communications that do not match the rules defined. You can find these system
policies displayed at the bottom of the list of rules.
1. To view these
policies, go to Modules and click on the Firewall icon. Then
click on the Edit Firewall Configuration icon. Scroll to the bottom of
the page and you will see the system policies.
2.
Click
on the icon to the left of the policy name you want to change. If the policy is
set to Allow all connections, clicking on this icon will deny all connections
and vice versa.
3.
To
apply the changes, click Activate, and then click Activate again.
Adding Custom Rules
This
section describes how you can create a custom rule for your firewall.
1.
Once
inside the Plesk control panel, click on Modules and then click on the Firewall
icon.
2.
Now
click on the Edit Firewall Configuration icon. You will find another
icon called Add Custom Rule; please click on this icon.

3.
Specify
the rule name, direction, action, and port. Then click on OK.

4.
Click
on Activate, and then click on Activate again.
Windows-based Plesk Firewall
Other
than using Windows Firewall with Advanced Security to manage your server
firewall inside your Window 2008 server, you can also use your Plesk control
panel to configure your firewall rules. Configuring a firewall for a specific
network interface is only available on a Windows 2003 server. For a Windows 2008
server, you will have to use the Firewall Rules tab to create or manage
firewall rules.
1.
Log
into your Plesk control panel with your Plesk login link. It will usually
follow this format: https://youriphere:8443. This will bring
up the Plesk login page.
2.
Once
logged in, you will then need to click on the Settings option under the Server
Management heading. Next, in the Security section, you will find a Firewall
option.


3.
In
the Tools section, click on the Switch On icon.

Create New Firewall Rule
Now that you
have turned on the firewall, you can create additional firewall rules.
1.
Click
on the Firewall Rules tab and then click on the Add Firewall Rule
icon.

2.
Specify
the rule name, the port number, and the protocol for which the incoming
connection must be allowed.

Note
that the tab next to the Firewall Rule tab, ICMP Protocol, is
used for network troubleshooting purposes. The predefined rules created for
ICMP communications are listed there. You can create rules to block or allow
the packets that match the rule.
Conclusion
Now
that you know how to manage your firewall using your Plesk panel, you can
create custom firewall rules. Apart from using Plesk to manage your firewall,
you can use in-built server tools to manage your firewall. For example, on a
Windows 2008 server you can use the Windows Firewall with Advanced Security tool.
In case of Linux, you can create firewall rules using iptables. If you
