Hi , thanks for the detailed bug report . that would be prefect if you add it under github issues.
For now one way is that you found your self to add dummy IP to linux to trick Mikrowizard as it gets IP list from interfaces and linux .the other workaround is to simply edit the code and add your IP to the list where MikroWizard finds IP list. from linux.

I added following to my todo list and feature request with high priority:
Add an option to add force custom peer ip.
