network – failed to display eth1. Maybe the gateway is a problem (with virtualBox)

I use parrot security v4.5 (I know it's not Ubuntu but maybe the solution to this problem is the same as that of Ubuntu) and here is my / etc / network / interfaces:

# This file describes the network interfaces available on your system.
# and how to activate them. For more information, see interfaces (5).

source /etc/network/interfaces.d/*

# The loop network interface
auto lo
iface lo inet loopback

# First interface
auto eth0
iface eth0 inet dhcp

# Second interface
auto eth1
iface wth1 static inet
address 20.0.0.2
network mask 255.255.255.0
gateway 20.0.0.1
20.0.0.0 broadcast

But when I do:

restarting the network service

I have this error:

The job for networking.service failed because the checkout process is complete with an error code.

And with:

service network status

J & # 39; have:

ifup: n failed to display eth1

If I delete the last three lines (if only the gateway lines are deleted, it does not work) in the file / etc / network / interfaces and that:

restarting the network service

then add only the netmask and the broadcast line with (NO gateway line):

restarting the network service

I have no problem.

What's the problem? Thank you.

N.B. Here is my configuration on the virtual box:
