MAC Address Definitions

Not Static Definitions, but the "MAC Address Definitions" under "Network Definitions" (right tab)... After creating a MAC Address Definition list, will using that definition from the drop down choice in a packet filter rule stop unauthorized use of the packet filter rule?

Or are the "MAC Address Definitions" only intended for wireless filtering?

Jim, you're understanding it correctly - it's a neat way to avoid creating a separate host with static mapping for each internal IP that you want to do something special with. You can just use "Internal (Network)" and limit the rule's application to a list of MAC addresses.

Unfortunately, since all external IPs come from the MAC of the last-hop router in front of your UTM, you can't use the same trick for public IPs.
