Noob help - Share internet connection over ethernet

[2late]

I want to share the wireless Internet connection from my 1 rig to my second rig via an ethernet port. will this work:

On the gateway

• Enable ip traffic forwarding:
  • Open /etc/sysctl.conf
  • Uncomment the line

COPY

net.ipv4.ip_forward=1

• Reload using sudo sysctl -p /etc/sysctl.conf
• Reconfigure ip_tables to allow NAT:
  • Download the attached file
  • Replace online_device with the name of the network device that provides the internet connection
  • Replace lan_device with the name of the network device that connects to the LAN
  • Run the script with sudo

On the client PC

Add the gateway PC as the default gateway using

COPY

sudo ip route del default
sudo ip route add default via <ip of gateway pc>

Add another DNS server to /etc/resolv.conf , for example

COPY

nameserver 8.8.8.8

thanks for any advice.
