Does anyone know if LnS is capable of blocking any attempt from intruders attempting to reach the same subnet as "my @" (my IP at my ISP)? How should I configure such a rule? For instance: My IP (my @) is 192.168.0.1 and the intruder is attempting to access my IP via the subnet such as 192.168.xxx.xxx, how can I block all access from any IP on my current subnet (my @)? I'm not sure how the "mask" function works in LnS, and am curious if the "mask" function in the "IP" dropdown menu would allow me to accomplish the above. Also, i've noticed that 'allowing all' ARP packets is not necessary for proper internet connection and use, however, i'm not sure what is considered a safe configuration. Does anyone have any guidelines to follow which allows a more secure "ARP" rule without degradation of security in F/W?
