Share wireless Internet connection through Ethernet on 18.04 LTS

Question

I've in the past successfully set sharing of wireless Internet connection through Ethernet on Ubuntu 16.04 as described here. Unfortunately due to disk failure I install Ubuntu 18.04 LTS and cannot find anything similar to what is described in mentioned post. All menus are now different and I don't know where to look.

Solution

Follows these steps:

1. Open nm-connection-editor from the terminal

   nm-connection-editor
   

2. Click on the wired connection and select edit cog wheel below

   

3. Go to the ipv4 settings tab there in the Method select Shared to Other Computers

Do you also need to install dnsmasq as a dhcp server for the ethernet client?

[George Udosen]

Not according to this article help.ubuntu.com/community/Internet/ConnectionSharing

Your link... under Advanced Gateway Configuration... re:dnsmasq... Advanced configurations include DHCP server and DNS server. A DHCP server allows the client to get an IP address automatically without having to manually configure a static IP. A DNS server allows the client to resolve Internet host names without manually configuring DNS addresses.

Keep in mind, that with dnsmasq AND systemd-resolved installed at the SAME time, adjustments need to be made on systemd-resolved so it can co-exist nicely.

I know what a DHCP server and what a DNS server do but I don't see the usefulness of setting up both just to share my internet with another computer!

Sorry, the earlier comment was just text copied directly out of your link... Didn't mean to offend. Anyway... either it's setup static IP/DNS addresses on the client... and hope they don't conflict with existing IP/DNS addresses already in use... or use something like dnsmasq to assign IP/DNS addresses.
