While learning some new things about iptables I can't through this. While I am trying to start, its saying as

 root@badfox:~# iptables -L -n -v

Chain INPUT (policy ACCEPT 0 packets, 0 bytes)

 pkts bytes target     prot opt in     out     source               destination         



Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)

 pkts bytes target     prot opt in     out     source               destination         



Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)

 pkts bytes target     prot opt in     out     source               destination         

root@badfox:~# service iptables stop

iptables: unrecognized service

root@badfox:~# service iptables start

iptables: unrecognized service

Why I am getting like this?

EDIT: So my firewall already started but why I am not getting the output as I mentioned in the link at source link in first workout.

Here is my output

root@badfox:~# sudo start ufw

start: Job is already running: ufw

root@badfox:~# iptables -L -n -v

Chain INPUT (policy ACCEPT 4882 packets, 2486K bytes)

 pkts bytes target     prot opt in     out     source               destination         



Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)

 pkts bytes target     prot opt in     out     source               destination         



Chain OUTPUT (policy ACCEPT 5500 packets, 873K bytes)

 pkts bytes target     prot opt in     out     source               destination         

root@badfox:~#

The Uncomplicated Firewall or ufw is the configuration tool for iptables that comes by default on Ubuntu. So if you wanted to start or stop the ufw service, you'd have to do something like this

#To stop

$ sudo service ufw stop

ufw stop/waiting



#To start

$ sudo service ufw start

ufw start/running

About why you are not receiving the output as shown in the source. It clearly states there that the output you are receiving is for an inactive firewall, that is, no rules have been set. So try setting up some rules in iptables. Here's the Ubuntu Wiki on iptables that shows you how to set, edit them and such.
