 The 

term DMZ (de-militarized zone), in Internet networking terms, refers to computers 

that are available for both public and in-network accesses (such as a company's public 

Web server). Packets received on a DMZ interface -- whether from a LAN or external 

source -- are subject to a set of protections that is in between public and private 

interfaces in terms of restrictiveness. The global setting for DMZ-type interfaces may be 

set to Deny so that all attempts to access these servers are denied by default; the 

administrator may then configure IP Filter rules to allow accesses of certain types. 

 

Bridge filter rules can be created to control the forwarding of incoming and outgoing data 

between your LAN and the Internet and within your LAN. Bridge filter rules make decisions 

based on the structure of the "layer 2" data packets (e.g., Ethernet packets) received on the 

device interfaces, unlike IP filter rules, which are based on the structure of "layer 3" (e.g., IP) 

packets. 

 

Rule ID: Each rule must be assigned an ID number. Rules are processed from lowest to 

highest on each data packet, until a match is found. Rule numbers up to 99 are reserved for 

preconfigured system rules. Rule IDs must start at 1000 or above so that they do not interfere
