It usually worked before when I connect two Linux machines through a LAN cable and set
Shared Internet Connection on the device whose internet I’d like to share. But it stopped working at some point (maybe my Linux installation is broken). I had to assign the IP and routes manually. Here are the settings for slave (master didn’t require any settings):
# Assign IP address to the client sudo ifconfig eth0 10.42.0.2 netmask 255.255.255.0 sudo ip route add default via 10.42.0.1
After this, internet started working and I could ping to 188.8.131.52. However, DNS has some problems. I’ll be editing this page if I can manage to make DNS work too.
