You can block anything that the software lets you configure. However, if
you start blocking your LAN IP addresses, wouldn't that stop your LAN from
working? I use Kerio Personal Firewall 2.1.5 behind a Netgear FR114p. I
have three trusted LAN IP addresses:

192.168.3.0/24
192.168.102.0/24
172.29.61.0/16

The only security implications in my configuration would be anybody who
physically connects to any segment; all segments are strictly wired.
Wireless has its own security implications apart from trusted IP addresses.

Device IP, the range of the allowed DHCP IP(s) and the Static IP of the
router were allowed to access the machines on the LAN. The personal FW on
all machines was configuerd to allow the traafic from the IP(s).

Notice that you're not using 192.168.1.x and not using 192.168.0.x as
trusted - that's really very good. If you always trust the two ranges
above may as well not have a firewall, since those are the default
ranges of most home routers and many businesses.

I don't run my home or any of the businesses we setup in the default
ranges of any of the Home/SOHO router devices, which means that when
people go to a hotel or another network it's very likely that they won't
default to allowing all communications.
