Tried it - does not make a difference. Besides, even

AllowUsers !root@*

alone does not work. I was not able to find a single instance where
negation would work.

Great idea! It does seem to accomplish what I need, but I have to use
multiple Match lines, like this:

PermitRootLogin no
Match Address 192.168.89.*
PermitRootLogin yes
Match Address 192.168.88.*
PermitRootLogin yes
....

BTW, negation does not work within Match block either...

Thanks a lot,

Andy
