Hitron CGNM-2250 User’s Guide
7.1.2
Device Filtering
Every networking device has a unique Media Access Control (MAC) address that
uniquely identifies it on the network. When you enable MAC address filtering on the
CGNM-2250’s firewall, you can set up a list of devices, identified by their MAC
addresses, and then specify whether you want to:
Deny the devices on the list access to the CGNM-2250 and the network (in
which case all other devices can access the network)
or
Allow the devices on the list to access the network (in which case no other
devices can access the network).
7.1.3
Service Filtering
Service filtering is a way of preventing users on the LAN from connecting with devices
on the WAN via specific services, protocols or applications. It achieves this by
permitting or denying traffic from the LAN to pass to the WAN, based on the target
port.
7.2

applications and protocols. You can select the level of firewall protection from pre-
