I know this is not a new question and it has been asked many times before. But, I could not find any documentation on how to do it on Ubuntu 19.04.
As any ordinary notebook computer I have a notebook with an Ethernet and a Wireless interface. I am using static local IP address on my Ethernet connection (because I am doing port forwarding from my router to my notebook). I want my notebook to have the same IP address whether it is connected to my LAN through Ethernet and/or Wireless. To do this (I think) I need to bond these two interfaces. In other words, regardless of how I connect my notebook computer to my LAN (i.e., using its wireless and/or Ethernet interface), the computer will use the same LAN IP address.
All the references I have found on the Internet are about older versions of Ubuntu. Newer versions of Ubuntu changed the way network configuration is done. So I tried to do this using Advanced Network Configuration tool (nm-connection-editor). However, after creating a new Bond virtual interface, the options to add "Bonded connections" in the Bond tab does not bring any Wi-Fi interface; only Ethernet, InfiniBand and other virtual connections are listed.
What am I doing wrong? Maybe I misunderstood the term. Maybe I am using it in the wrong way.
Note: Any other suggestions on how to use the same IP address on these two interfaces are welcome.
