5.8 Access Control
5.8.1 Local IP Filtering
- Gateway Mode only
Broadband Router allows you to do accessed restriction of block/allow
outgoing IP packets by protocol ( port number).
You may restrict some IPs only 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 allows you set ten items and item 1 has the highest
priority. In principle, the same IP should not list in different items. If IP settings
confliction occurs, item with higher priority would be the obeyed rules.
You can reserve dedicate IP address to dedicated user from “ Configure
LAN ” display -> “ 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.
Example 1 , if you restrict the PC of IP 192.168.1.13-192.168.1.15 to access
HTTP, the settings are:
Item 1: Enable
Filter entry: Block
Port Number: 80
IP address: 192.168.1.13-192.168.1.15

FTP only, the settings are:
Item 2: Enable
Filter entry: Allow

IP address: 192.168.1.16-192.168.1.18
Example 3 , if you allow the PC of IP 192.168.1.40, 192.168.1.56,
192.168.1.100-192.168.1.120 to access port 50, port53, port100-120 only, the
