How to check the IP:PORT firewall uses?
I have my firewall process running

Code:
[root@development_techx tmp]# ps -ef | grep firewall
root     21169     1  0 08:50 ?        00:00:00 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid

I wish to know what ip : port number it is using. Can you please tell me how can i find out ?

I tried the below command but does not seem to give me a port number in the output:
Code:
netstat -anp | grep 21169
unix  3      [ ]         STREAM     CONNECTED     771780   21169/python

This will help me monitor if the firewall service is running or not from a remote monitoring server or a monitoring system like Uptime Robot

Can you please tell me how can i find out what port number; is the firewall process listening ON; inorder to monitor the firewall service from a remote system?

firewall-applet

FIREWALL-APPLET(1)						  firewall-applet						FIREWALL-APPLET(1)

NAME

       firewall-applet - firewalld applet

SYNOPSIS

       firewall-applet [OPTIONS...]

DESCRIPTION

       firewall-applet is a tray applet for firewalld.

OPTIONS

       firewall-applet does not support any special options. The only options that can be used are the general options that Gtk uses for Gtk
       application initialization. For more information on these options, please have a look at the runtime documentation for Gtk.

       The following options are supported:

       -h, --help
	   Prints a short help text and exists.

GSETTINGS

       firewall-applet has additional settings to adapt the look and feel. The used backend depends on the distribution and can be either dconf or
       GConf. The path to the settings is org.fedoraproject.FirewallApplet. You can use dconf-editor or gconf-editor to see and modify them.

       The following settings are supported:

       notifications
	   The applet shows notifications if enabled. This setting can be enabled also in the applet with the "Enable Notifications" checkbox in
	   the right mouse menu.

	   This setting defaults to false.

	   If notifications are shown for these actions if enabled:

	   o   Connection to firewalld established

	   o   Connection to firewalld lost

	   o   Firewall has been reloaded

	   o   Default zone has been changed

	   o   Panic mode has been enabled or disabled

	   o   Activation, deactivation or change of zones bound to interfaces

	   o   Activation, deactivation or change of zones bound to sources addresses

       show-inactive
	   Show applet also if firewalld is not running. If firewalld has been stopped or is not running the applet will be hidden and not visible
	   in the applet tray. Enable this setting to see the applet all the time for example to be sure that the firewall is active.

	   This setting defaults to false.

       shields-up
	   The shields-up zone name to be used if shields-up is enabled.

	   This setting defaults to 'block'.

       shields-down
	   The shields-down zone name to be used if shields-up has been deactivated again.

	   This setting defaults to 'public'.

       blink
	   If enabled, the applet icon blinks in these cases:

	   o   Connection to firewalld lost

	   o   Panic mode has been enabled or disabled

	   This setting defaults to false.

       blink-count
	   The number of blinks if blink is enabled.

	   This setting defaults to 5.
