Virtual Machine Not Allowing Arpspoofing?

Hi! I have talked about this issue a lot. I do not have a wireless adapter but it seems that does not cause an issue. I am trying to perform a mitm attack on my kali linux and I enable ip forwarding and ettercap and everything and my target's computer's connection to the internet is killed.

These are the commands I type:

echo '1' > /proc/sys/net/ipv4/ip_forward

ettercap -G

(I choose eth0 as my interface to use)

(I choose my options and targets)

(I chose man in the middle and sniff remote connections)

(I start sniffing)

and this is where my target's connection is lost.

Here are my network settings for my vm:

Any help is appreciated. Thanks!
