IP Filter
IP filters (also called a rule set) act as a firewall to allow or deny an individual MAC address or
individual or a range of IP addresses, ports, and protocols. When a network connection is
configured to use an IP filter, all network traffic through that connection is compared, in order, to
the rules of that filter. Network traffic may be allowed to pass, it may be dropped (without notice),
or it may be rejected (sends back an error packet) depending upon the rules of that filter rule set.
The administrator uses the
page to view, add, edit, delete, and map IP filters.
Warning:
IP filters configuration is a feature for advanced users. Adding and
enabling IP filter sets incorrectly can disable access to your EMG unit.
