Firewall rule for incoming SSH: Network/mask setting for endpoint

Hello,

I'm using Kerio Personal Firewall 2.1.5.

When I ssh in from another computer, I am prompted for incoming TCP to port 22,
connecting to c:\Path\Of\SSHD\Server from The.Remote.IP.address. So I created a
rule for exactly that, except that I specified that the allowable remote IPs to be

Network Address: xxx.yyy.zzz.www
Network Mask: 255.255.255.0

From confirming on usenet, this specifies IPs where www ranges from 0-255. This
is the behaviour that I wanted, since, the IPs are assigned dynamically. It
also seemed to work fine at the time that I created the rule.

However, it stopped working today. I specified the IP address as a range, and
it started to work again. Then changed to back to network/mask -- still
continued working.

Any ideas as to what might cause this?

Thanks.

It is broken software?
Someone hacked it?
Someone circumvented it?
