Using kali linux for this.
I went into the "Network Connections" and created a new connection under "Wired" and set it to "Shared to other computers" under the "IPv4" tab and it doesn't work. When I plug it into my Mac it shows the ip is self-assigned. Now when I load up kali linux on my laptop and do the same exact thing, it works. What am I doing wrong? Or is there an easier way to set this up?
EDIT: Tried using bridge-utils by running the following commands:
brctl addbr br0 brctl addif br0 eth0 eth1
and get an error message:
Operation not supported
