3.8 Access Control
3.8.1 Local IP Filtering
AirLive IGR-2500 allows you to define the accessed restriction about to block or allow outgoing IP packets per
protocol (port number).
You may restrict specific IP to perform limited protocols or allow them to execute partial protocols. And the first
thing you have to know is the port numbers and their usages.
Local IP Filtering can be defined 10 items and item 1 has the highest priority. In principle, the same IP should
not list in different items. If IP settings are conflicted, the higher priority item will be the obeyed rules.
You can reserve dedicate IP address to dedicated user from Configure LAN & DHCP Æ Reservations IP
function, by using this function, user can have dedicated IP address match to their computer NIC MAC
address.
There are ten items in this function. You can allow or restrict specific IP(s) to access some port numbers.
