Could it be that the Subnet declaration was on the last line of the
file? There is a bug in 1.0.13 (fixed in 1.0.14) that causes it to
ignore the last line of a config file if it doesn't end with a newline
character. You might have fixed it when you replaced it with two /9
Subnets. If so, try changing it back to one /8 again.

Otherwise, there is no lower limit. You can in fact add Subnet =
0.0.0.0/0, which is used for example in this example:
