Subject: IPs and masks
Exactly what does 192.168.1.0/255.255.255.0 mean? I always thought it meant
the 1st three octets (?) must match but that the fourth could be any value.
IOW, having my firewall show this network being in the trusted zone meant
any IP from 192.168.1.1 to 192.168.1.255 would be in the zone (I think the
other value means something special).

Can someone correct me? Something isn't working as the 192.168.1.105 system
is apparently being blocked from writing to shared disk on 192.168.1.101 by
the firewall on 101 which shows the above being in the trusted zone.
