(I missed seeing this earlier - - - apologies!!!)

Thanks mr Tito!!

This idea appeals a lot - - - except - - I haven't been able to find anything
to even outline how to configure opnsense from the command line - - -
I've looked.
If I could find that information I'd be busy - - - but it would get done!!!

(Great idea - - - now to find a cheat sheet.)
