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.

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
