Hello,
I have a virtual machine with two NICs as follows:

I want to share the internet of the enp0s3 NIC with the enp0s8 NIC. I used the following iptables rules:
Code:$ sudo iptables -I INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
$ sudo iptables -I FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
$ sudo iptables -t nat -I POSTROUTING -o enp0s3 -j MASQUERADEAfter it, when I use the IP address 192.168.1.20 as the default gateway on another machine, then that machine has access to the Internet. This means that the Internet is properly shared, but Why does the following command not work?
Code:$ ping -I enp0s8 8.8.8.8Thank you.
