IP/Port filtering

In this section, you can configure filtering rules to restrict certain types of data packets from
passing through the ONT. The use of such filters can be helpful in securing or restricting your local
network.
LAN WAN: By default, all outgoing traffic from LAN is allowed, but some can be blocked by
−
specific filtering rules. Outgoing filtering rules can block outgoing traffic by some conditions.
WAN LAN: By default, all incoming traffic is blocked. However, some traffic can access by
−
specific filtering rules. The incoming filtering rules allow traffic to pass in some conditions.
To access the configuration page, log in to the web UI of the ONT and choose Services > Firewall >
IP/Port Filtering. The rules added are shown in the Current Filter Table.
