Hi Mark,

I think you should recalculate your subnets.  When you use something 
like the following:

   192.168.0.1/255.255.255.0

This takes every access attempt, let's use the source IP of 192.168.0.2 
for an example, and performs a logical AND with the netmask to determine 
whether or not access should be allowed, and compares that to the 
network definition of the Allow line in your config.

   192.168.0.2 ANDed with 255.255.255.0 = 192.168.0.0

..so this does not match!  The network in your allow line is 192.168.0.1.

On the other hand, if you change your allow line to the following:

   Allow 192.168.0.0/255.255.255.0

..and perform the same calculation:

   192.168.0.2 ANDed with 255.255.255.0 = 192.168.0.0

..you would be granted access.
